This is a book about some of the lesser known effects of meditation that have been considered magic or esoteric in western cultures for a long time. If this were the fifteenth century rather than the twenty first this book might be considered a grimoire or collection of spells and practices for gaining power over the material world. However, this is a book about gaining or developing esoteric energy sometimes called spiritual power, Kundalini, shakti, the Holy Spirit, chi, ki, pneuma, et cetera, ad on, ad-infinitum.
