It is shown in this article that many positions that are usually considered incompatible or antagonistic can be synthesized into a unified framework, creating a model of transpersonal development based around plurality and complexity. The model focuses on evolutionary developmental biology as well as around psychological theories. A large degree of variability in the nature of transpersonal experience in the life cycle is to be expected, due to differences in both the “timing of onset” of transpersonal characteristics and the “length (...) of developmental period.” Numerous developmental patterns are identified, using the work of some prominent transpersonal theorists.

This article considers the psychology of meditation and other introverted forms of mystical development from a neo-Piagetian perspective, which has commonalities with biogenetic structuralist and neurotheological approaches. Evidence is found that lines of meditative development unfold through Patañjali’s stages at different rates in an echo of the unfolding of lines of cognitive development through Piaget’s stages at different rates. Similar factors predicting the degree of independence of development apply to both conventional cognitive and meditative contents. As the same brain and (...) the same nervous system are involved in both cognitive developmental psychology and meditation there are likely to be commonalities between conventional psychological and transpersonal development. Neo-Piagetian transpersonal psychology predicts a variable landscape of spiritual development across traditions and individuals, in line with variability in the cultural learning environment. (shrink)
