The first part of the chapter begins by defining transpersonal development and how a transpersonal perspective differs from traditional approaches. The chapter explains why spiritual development is a transpersonal concern and how spiritual (transpersonal) development is influenced by gender and culture. The chapter explores ego-transcendence and ego-transformation as aspects of transpersonal development best expressed through symbol, metaphor, poetry, art, and music. The chapter then examines the variety of forms that transpersonal development can take. The second part of the chapter explores aspects of transpersonal development across the lifespan. This includes childhood spirituality, the challenges of research into children’s spiritual experiences, and the transpersonal possibilities of childhood. The chapter then explores conscious aging in adulthood and the elder years. This includes an examination of the fields of transpersonal gerontology and gerotranscendence. This is followed by an experiment in re-visioning one’s understanding of one’s own past. The chapter then examines death awareness and death anxiety and transpersonal approaches to the care of the dying. The chapter ends by exploring the death experience as represented in near-death experiences, the Tibetan Book of the Dead, altered states of consciousness, and phenomena suggestive of the personal survival of consciousness.
