As a foundation for discussing transpersonal adult development, the author traces her trajectory, involvement in, and contribution to the modern transpersonal movement and her introduction of it to the adult learning literature, beginning during the early 1980s. Highlighted are the transpersonal domain and a differentiation between transpersonal development that may be methodically pursued (consciously raised) and spontaneous occurrences that may leave one bewildered. Beyond the individual, transpersonal development also applies to relationships, organizations, communities, and the cosmos. Moreover, one's individual transpersonal development can influence the collective and vice versa. Considerations for adult learning are offered.
