An ancient insight about higher human development states very simply: psychic development is not the same as spiritual growth. In the course of one's spiritual growth-i.e., actualizing your potential for higher human development-there are dangers, dead-ends, byways and traps of which to beware. A principal source of such difficulties is the failure to distinguish between the psychic and the spiritual. This lesson-the psychic is not the spiritual-has been given major emphasis in the teaching of all the world's major spiritual and religious traditions. All sacred traditions have made explicit warnings about it and have formulated doctrinal statements and instructional practices to guide people safely along the path to enlightenment and God-realization. This book can help you to become more sensitive to the spiritual realm, to distinguish it from the psychic realm, and to be more knowledgeable about both. I also offer what I think are sensible, prudent cautions which ought to be taken by those who seek psychic development.
