Sattva is the natural quality of the mind, Rajas of the life-force and Tamas of the physical body. All Yoga consists in reducing Rajas and Tamas from the mind to bring it to a state of pure Sattva. Pure Sattva, or the mind in its natural state, has the power to perceive truth, to reflect the seer or the Purusha. It believes in using the principles of nature to bring an individual back into equilibrium with their true self. Ayurveda looks at life from an energy perspective.
Health is the harmony between the energy components of body, mind and spirit.
The Ayurvedic approach to disturbances in the mental and spiritual aspects of an individual, aims first to harmonise the physical body and then to expand that harmony to the mind and the spirit. The Yogic approach involves working with the spirit to induce the body and the mind to become harmonised. The Yogic diet aims to take predominantly Sattvic food, living in a Sattvic environment, associating with Sattvic people and having a generally Sattvic life-style. Sattvic food is vegetarian, fresh, organic and prepared with love. A Sattvic environment is natural, pure, quiet and harmonious.
