A short definition from the Journal of Transpersonal Psychology suggests that transpersonal psychology "is concerned with the study of humanity's highest potential, and with the recognition, understanding, and realization of unitive, spiritual, and transcendent states of consciousness". Issues considered in transpersonal psychology include spiritual self-development, self beyond the ego, peak experiences, mystical experiences, systemic trance and other sublime and/or unusually expanded experiences of living.
Transpersonal psychology developed from earlier schools of psychology including psychoanalysis, behaviorism, and humanistic psychology. Transpersonal psychology attempts to describe and integrate spiritual experience within modern psychological theory and to formulate new theory to encompass such experience. Types of spiritual experience examined vary greatly but include mysticism, religious conversion, altered states of consciousness, trance and spiritual practices. Although Carl Jung, Otto Rank and others explored aspects of the spiritual and transpersonal in their work, Miller notes that Western psychology has had a tendency to ignore the spiritual dimension of the human psyche.
 Origins and definition of the discipline
Lajoie and Shapiro reviewed forty definitions of transpersonal psychology that had appeared in literature over the period 1969 to 1991. They found that five key themes in particular featured prominently in these definitions: states of consciousness, higher or ultimate potential, beyond the ego or personal self, transcendence, and the spiritual. Walsh and Vaughan have criticised many definitions of transpersonal psychology, for carrying implicit ontological or methodological assumptions. They also challenge definitions that link transpersonal psychology to healthy states only, or to the "Perennial Philosophy". These authors define transpersonal psychology as being the branch of psychology that is concerned with transpersonal experiences and related phenomena, noting that "These phenomena include the causes, effects and correlates of transpersonal experiences, as well as the disciplines and practices inspired by them."
Caplan (2009: p. 231) conveys the genesis of the discipline, states its mandate and ventures a definition:
Although transpersonal psychology is relatively new as a formal discipline, beginning with the publication of The Journal of Transpersonal Psychology in 1969 and the founding of the Association for Transpersonal Psychology in 1971, it draws upon ancient mystical knowledge that comes from multiple traditions. Transpersonal psychologists attempt to integrate timeless wisdom with modern Western psychology and translate spiritual principles into scientifically grounded, contemporary language. Transpersonal psychology addresses the full spectrum of human psychospiritual development -- from our deepest wounds and needs, to the existential crisis of the human being, to the most transcendent capacities of our consciousness.—Caplan, Mariana (2009).

 Development of the academic field
Amongst the thinkers who are held to have set the stage for transpersonal studies are William James, Carl Jung, Otto Rank, Abraham Maslow, and Roberto Assagioli. Research by Vich suggests that the earliest usage of the term "transpersonal" can be found in lecture notes which William James had prepared for a semester at Harvard University in 1905-6. Another important figure in the establishment of transpersonal psychology was Abraham Maslow. Maslow had already published work regarding human peak experiences, and was one of the people, together with Stanislav Grof and Viktor Frankl, who suggested the term "transpersonal" for the emerging field. Gradually, during the 1960s, the term "transpersonal" was associated with a distinct school of psychology within the humanistic psychology movement.
In 1969, Abraham Maslow, Stanislav Grof and Anthony Sutich were among the initiators behind the publication of the first issue of the Journal of Transpersonal Psychology, the leading academic journal in the field. This was soon to be followed by the founding of the Association for Transpersonal Psychology (ATP) in 1972. Past presidents of the association include Alyce Green, James Fadiman, Frances Vaughan, Arthur Hastings, Daniel Goleman, Robert Frager, Ronald Jue, Jeanne Achterberg and Dwight Judy. In the 1980s and 90s the field developed through the works of such authors as Jean Houston, Stanislav Grof, Ken Wilber, Michael Washburn, Frances Vaughan, Roger Walsh, Stanley Krippner, Michael Murphy, Charles Tart, David Lukoff, Vasily Nalimov, Margret Rueffler and Stuart Sovatsky. While Wilber has been considered an influential writer and theoretician in the field, he has since personally dissociated himself from the movement in favor of what he calls an integral approach.
By common consent, the following branches are considered to be transpersonal psychological schools: various depth psychology approaches including Analytical psychology, based on Carl Jung, and the Archetypal psychology of James Hillman; the spiritual psychology of Robert Sardello,; psychosynthesis founded by Roberto Assagioli; Zen Transactional Psychotherapy created by Robert M. Anthony (Creative Psychotherapy, 1976), and the theories of Otto Rank, Abraham Maslow, Stanislav Grof, Timothy Leary, Ken Wilber, Michael Washburn and Charles Tart.
Although the majority of mainstream psychology departments, as part of their curriculum, rarely offer training programs in transpersonal issues and practices, Transpersonal perspectives are starting to be applied to such diverse fields as psychology, psychiatry, anthropology, sociology, pharmacology, and social work theory. Transpersonal therapies are also included in many therapeutic practices. Currently, transpersonal psychology, especially the schools of Jungian and Archetypal psychology, is integrated, at least to some extent, into many psychology departments in American and European Universities. Institutions of higher learning that have adopted insights from transpersonal psychology include The Institute of Transpersonal Psychology (US), California Institute of Integral Studies (US), John F. Kennedy University (US), Saybrook University (US), University of West Georgia (US), Atlantic University (US), Burlington College (US), Essex University (UK), Liverpool John Moores University (UK), the University of Northampton (UK), Leeds Metropolitan University (UK), Naropa University (Colorado), Pacifica Graduate Institute (CA), and Southwestern College (NM). There is also a strong connection between the transpersonal and the humanistic approaches to psychology. This is not surprising since transpersonal psychology started off within humanistic psychology. In 1996 the British Psychological Society (the UK professional body equivalent to the APA) established a Transpersonal Psychology Section. It was co-founded by David Fontana, Ingrid Slack and Martin Treacy, and was according to Fontana "the first Section of its kind in a Western scientific society".
Robert Frager, of the Institute of Transpersonal Psychology, and James Fadiman, of the Institute of Transpersonal Psychology, provide an account of the contributions of many of the key historic figures who have shaped and developed transpersonal psychology (in addition to discussing and explaining important concepts and theories germane to transpersonal psychology) in a textbook on personality theories which serves to promote an understanding of the discipline in classroom settings. An example which points to the possibility that awareness and discussion of transpersonal psychology in mainstream classroom settings may be on the rise can be seen by the inclusion of a section on transpersonal psychology for the first time in a textbook by Barbara Engler in which she asks the question, "Is spirituality an appropriate topic for psychological study?" Engler offers a brief account of the history of transpersonal psychology and a peek into its possible future in noting that G-H Jennings (1999) "suggests that transpersonal psychology, using Jung's typology, expresses the neglected inferior function in American psychology, needs to be incorporated into it, and offers great potential and promise for the development of psychology in the third millennium".
Transpersonal psychology is many times regarded as the fourth wave force of psychology which according to Maslow even transcends the self-actualization of Humanistic psychology(1968). Unlike the other first three schools of psychology i.e. psychoanalysis, behaviorism and humanistic psychology which more or less deny the transcended part of soul, transpersonal psychology integrates the whole spectrum of human development from prepersonality to transpersonality. Hence transpersonal psychology can be considered the most integrated complete psychology, a positive psychology par excellence. From personality to transpersonality, mind to meditation, neuroscience to Nirvana it is a complete wholesome science for all round development and treatment.
Transpersonal psychology can be confused with Parapsychology. This may sometimes happen due to the overlapping and unconventional research interests of both fields. In short; parapsychology tends to focus more in its subject matter on the "psychic", while transpersonal psychology tends to focus on the "spiritual" (relatively crude though these categorizations are, it is still a useful distinction in this context). While parapsychology leans more towards traditional scientific epistemology (laboratory experiments, statistics, research on cognitive states), transpersonal psychology tends to be more closely related to the epistemology of the humanities and the hermeneutic disciplines (humanism, existentialism, phenomenology, anthropology), although it has always included contributions involving experimental and statistical research.
Transpersonal psychology may also, sometimes, be associated with New Age beliefs. Although the transpersonal perspective has many overlapping interests with theories and thinkers associated with the term "New Age", it is still problematic to place transpersonal psychology within such a framework. Transpersonal psychology is an academic discipline, not a religious or spiritual movement, and some of the field's leading authors, among those Sovatsky, have criticized the nature of New Age discourse. Associations between transpersonal psychology and the New Age have probably contributed to the failures in the United States of America to get transpersonal psychology more formally recognised within the professional body, the American Psychological Association (APA).
The transpersonal perspective spans many research interests. The following list is adapted from the Textbook of Transpersonal Psychiatry and Psychology and includes:

 Contributions to the academic field
Transpersonal Psychology has made several contributions to the academic field, and the studies of human development, consciousness and spirituality. Transpersonal Psychology has also made contributions to the field of psychiatry. One of the demarcations in transpersonal theory is between authors who present a fairly linear and hierarchical model of human development, such as Timothy Leary and Ken Wilber, and authors who present non-linear models of human development, such as Michael Washburn and Stanislav Grof. Timothy Leary, who was originally a professional psychologist and a professor of psychology, made a significant contribution to transpersonal psychology with the formulation of his "Eight Circuit Model of Consciousness", outlined in his book Info-Psychology.
Ken Wilber's primary contribution to the field is the theory of a spectrum of consciousness consisting of three broad categories: the prepersonal or pre-egoic, the personal or egoic, and the transpersonal or trans-egoic. A more detailed version of this spectrum theory includes nine different levels of human development, in which levels 1-3 are pre-personal levels, levels 4-6 are personal levels and levels 7-9 are transpersonal levels. Later development of the theory also includes a tenth level. Wilber has portrayed the development of human consciousness as both hierarchical and circular. His model is hierarchical in the way that development progresses from matter to body to mind to spirit. It is circular and uneven in the sense that the various developmental lines (e.g. morality, cognition, emotion, self-sense, etc.) don't always develop in tandem and thus progress can involve circling back to pick up the process. According to this theory different schools of psychology address different levels of the spectrum. Also, each level of organization, or self-development, includes a vulnerability to certain pathologies associated with that particular level. That is, developmental tasks must be properly met or they might lead to developmental arrest.
Wilber also describes a situation called the "pre/trans fallacy". According to Transpersonal theorists western schools of psychology have had a tendency to dismiss or pathologize transpersonal levels, equating them with regressive pathological conditions belonging to a lower level. The pre/trans fallacy describes a lack of differentiation between pre-rational psychiatric problems and valid transpersonal problems.
In contrast to Leary and Wilber, Michael Washburn and Stanislav Grof present models of human development that are not hierarchical or linear. Washburn presents a model that is informed by the Jungian perspective, and brings forth the notion of a U-turn. In other words, he introduces the idea of "integration through regression". That is, regression in the service of transcendence.
Central to this model is the idea that the ego initially arose out of a "source" or "ground". Therefore, transpersonal development requires a return to this origins, before it can move on. Or as formulated by Sharma, Charak and Sharma: ego revisits its nascent pre-ego origins in the unconscious in order to become integrated with its source and thereby transcend.
Grof, on the other hand, operates with a cartography consisting of three kinds of territories: the realm of the sensory barrier and the personal unconscious (described by psychoanalysis), the perinatal or birth-related realm (organizing principles for the psyche), and the transpersonal realm. According to this view proper engagement with the first two realms sets the stage for an ascent to the third, transpersonal, realm. Grof applies regressional modes of therapy (originally with the use of psychedelic substances, later with other methods) in order to seek greater psychological integration. This has led to the confrontation of constructive and deconstructive models of the process leading to genuine mental health: what Wilber sees as a pre/trans fallacy does not exist for Washburn and Grof, for pre-rational states may be genuinely transpersonal, and re-living them may be essential in the process of achieving genuine sanity.
As an alternative to many of the major epistemological and philosophical trends in the field, such as the focus upon experientialism (inner spiritual states) and perennialism (the legacy of the perennial philosophy), Ferrer has suggested a revision of Transpersonal Theory that focuses more upon the great variety, or pluralism, of spiritual insights and spiritual worlds that can be disclosed by transpersonal inquiry. He calls this revision a "participatory turn".
Transpersonal Psychology has also brought clinical attention to the topic of spiritual crisis. A spiritual crisis has to do with a person's relationship to existential issues, or issues that transcend the mundane issues of ordinary life. Many of the psychological difficulties associated with a spiritual crisis are not ordinarily discussed by mainstream psychology. Among these problems are psychiatric complications related to mystical experience, near-death experience, Kundalini awakening, shamanic crisis (also called shamanic illness), psychic opening, intensive meditation, and medical or terminal illness.
The terms "Spiritual Emergence" and "Spiritual Emergency" were coined by Stanislav and Christina Grof in order to describe a spiritual crisis in a person's life (precedents of Grof's approach in this regard are found in Jung, Perry, Dabrowski, Bateson, Laing, Cooper and antipsychiatry in the widest sense of the term). The term "Spiritual emergence" describes a "gradual unfoldment of spiritual potential with no disruption in psychological-social-occupational functioning". In cases where the spiritual unfoldment is intensified beyond the control of the individual it may lead to a state of "Spiritual Emergency". A Spiritual Emergency may cause significant disruption in psychological, social and occupational functioning. Many of the psychological difficulties described above can, according to Transpersonal theory, lead to episodes of spiritual emergency.
Because of the overlap of spiritual crisis and mental health problems, Transpersonal Psychologists made a proposal for a new diagnostic category entitled "Psychoreligious or Psychospiritual Problem" at the beginning of the 1990s. The category was approved by the DSM-IV Task Force in 1993, after changing the title to "Religious or Spiritual Problem". It is included in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). According to Chinen the inclusion marks "increasing professional acceptance of transpersonal issues". Besides signifying a greater sensitivity towards spiritual issues, and spiritually oriented narratives, the new V-Code may also contribute to the greater cultural sensitivity of the manual and could help promote enhanced understanding between the fields of psychiatry and religion/spirituality.
Criticisms of transpersonal psychology have come from several commentators. One of the earliest criticisms of the field was issued by the Humanistic psychologist Rollo May, who disputed the conceptual foundations of transpersonal psychology. Another early criticism regarded the relationship between Transpersonal Psychology and the ideas of William James. Although the ideas of James are central to the Transpersonal field, Alexander thought that Transpersonal Psychology did not have a clear understanding of the negative dimensions of consciousness (such as evil) expressed in James' philosophy. This serious criticism has been absorbed by later Transpersonal theory, which has been more willing to reflect on these important dimensions of human existence. Criticism has also come from the cognitive psychologist and humanist Albert Ellis, who has questioned transpersonal psychology's scientific status and its relationship to religion and mysticism. Friedman has criticized the field of Transpersonal psychology for being underdeveloped as a field of science, placing it at the intersection between the broader domain of inquiry known as transpersonal studies (which may include a number of unscientific approaches) and the scientific discipline of psychology. Ferrer has criticized Transpersonal Psychology for being too loyal to the perennial philosophy, for introducing a subtle Cartesianism, and for being too preoccupied with intrasubjective spiritual states (inner empiricism). As an alternative to these trends he suggests a revision of transpersonal theory. That is, a participatory vision of human spirituality that honors a wide assortment of spiritual insights, spiritual worlds and places.
From the standpoint of Buddhism and Dzogchen, Elías Capriles has objected that transpersonal psychology fails to distinguish between the transpersonal condition of nirvana, which is inherently liberating, those transpersonal conditions which are within samsara and which as such are new forms of bondage (such as the four realms of the arupyadhatu or four arupa lokas of Buddhism, in which the figure-ground division dissolves but there is still a subject-object duality), and the neutral condition in which neither nirvana nor samsara are active that the Dzogchen teachings call kun gzhi (in which there is no subject-object duality but the true condition of all phenomena (dharmata) is not patent (and which includes all conditions involving nirodh or cessation, including nirodh samapatti, nirvikalpa samadhis and the samadhi or turiya that is the supreme realization of Patañjali's Yoga darshana). In the process of elaborating what he calls a meta-transpersonal psychology, Capriles has carried out conscientious refutations of Wilber, Grof and Washburn, which according to Macdonald & Friedman will have important repercusions on the future of transpersonal psychology.
Doctrines or ideas of many colorful personalities, who were or are spiritual teachers in the Western world, such as Gurdjieff or Alice Bailey, are often assimilated into the transpersonal psychology mainstream scene. This development is, generally, seen as detrimental to the aspiration of transpersonal psychologists to gain a firm and respectable academic status. It could also be argued that most psychologists do not hold strictly to traditional schools of psychology — most psychologists take an eclectic approach. This could mean that some of the transpersonal categories listed above are considered by standard subdisciplines of psychology; religious conversion falling within the ambit of social psychology, altered states of consciousness within physiological psychology, and spiritual life within the psychology of religion. Transpersonal psychologists, however, disagree with the approach to such phenomena taken by traditional psychology, and claim that transpersonal categories have typically been dismissed either as signs of various kinds of mental illnesses, or as a regression to infantile stages of psychosomatic development. Thus, as illustrated by the pre/trans fallacy, religious and spiritual experiences have in the past been seen as either regressive or pathological and treated as such.
Transpersonal psychology has been applied to areas such as counselling, health, spiritual development, mind expansion, and to provide psychological security for self growth. Applications to the areas of business studies and management have been developed. Other transpersonal disciplines, such as transpersonal anthropology and transpersonal business studies, are listed in transpersonal disciplines.
Stanislav Grof's approach to transpersonal psychology has close connections to the field of archetypal cosmology. Working with his colleague Richard Tarnas, Grof found that the qualitative, thematic content of altered states of consciousness could be illuminated using archetypal astrology. Grof's collaboration with Tarnas has also identified correlations between the stages of Grof's model of perinatal psychology (the Perinatal Matrices) and themes associated with certain planetary archetypes.
Transpersonal art is one of the disciplines considered by Boucovolas, in listing how transpersonal psychology may relate to other areas of transpersonal study. In writing about transpersonal art, Boucovolas begins by noting how, according to Breccia and also to the definitions employed by the International Transpersonal Association in 1971, transpersonal art may be understood as art work which draws upon important themes beyond the individual self, such as the transpersonal consciousness. This makes transpersonal art criticism germane to mystical approaches to creativity. Transpersonal art criticism, as Boucovolas notes, can be considered that which claims conventional art criticism has been too committed to stressing rational dimensions of art and has subsequently said little on art's spiritual dimensions, or as that which holds art work has a meaning beyond the individual person. Certain aspects of the psychology of Carl Jung, as well as movements such as music therapy and art therapy, may also relate to the field. Boucovolas' paper cites Breccia (1971) as an early example of transpersonal art, and claims that at the time his article appeared, integral theorist Ken Wilber had made recent contributions to the field. More recently, the Journal of Transpersonal Psychology, in 2005, Volume 37, launched a special edition devoted to the media, which contained articles on film criticism that can be related to this field.

Among these problems are experiences related to changing denomination, conversion to a new religion, intensification of religious belief or practice, loss or questioning of faith, and joining or leaving a new religious movement or cult (Lukoff, Lu & Turner, 1996:234)
