A few small attempts have been made to introduce Transpersonal psychology to the classroom setting. Perspectives from transpersonal psychology are represented in a widely used college textbook on personality theories, marking the entrance of transpersonal themes into mainstream academic settings. In this book author Barbara Engler asks the question, "Is spirituality an appropriate topic for psychological study?" She offers a brief account of the history of transpersonal psychology and a peek into its possible future. The classroom dimension is also present in a book on personality theories by authors Robert Frager and James Fadiman. In this publication they 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 it), which serves to promote an understanding of the discipline in classroom settings.
