Patanjali’s short volume is considered to be a classic of yoga philosophy. Defining yoga as “the restraining of the agitations natural to mind,” patanjali proceeds with a series of concise one-ine statements the demonstrate how the goal of this discipline is to be won. The progressive stages of mind control, contemplation, spiritual disciplines, divine powers, and realization are revealed and mapped with their accompanying landmarks. The quotations from Swami both explicate and supplement the original teachings.
