If you really want to take advantage of the power of yoga, you need to understand its source. The path of yoga is firmly rooted in Indian philosophy—the philosophy of the Vedas—but this philosophy is not just Indian. It is timeless and universal and contains knowledge of the indestructible inner reality gained by great seers through yogic disciplines. Ishan explains that the Vedas and Vedic systems of philosophy are the pinnacle of human wisdom developed over thousands of years by a culture extending far beyond the Indian subcontinent. Patanjali’s Yoga Sutra is the culmination of this knowledge.
