The Yoga Aphorisms of Patanjali

The Soul is the friend of Self and also its enemy; and that a man should raise the self by the self.This book is meant for sincere students and especially for those who have some glimmering of what Krishna meant when in Bhagavad-Gita he said that after a while spiritual knowledge grows up within and illuminates with its rays all subjects and objects. Patanjalis rules compel the student not only to acquire a right knowledge of what is and what is not real but also to practice all virtues.
