Yoga is the science of union with the Divine, with Truth: Tantra is the most direct methodof controlling the energy that creates the ultimate union with Truth; and Ayurveda is the science of life.

According to the teachings of Ayurveda, every human being has four biological and spiritual instincts: religious, financial, procreative and the instinct toward freedom.

Yoga claims to provide a system by which the practitioner can directly realize his or her puruṣa, the soul or innermost conscious self, through mental practices.
