The ancient Indian masters and mystics were experts in the mind and consciousness. They experienced deep mental processes through inner vision and viewed the world we live in as an illusion. By striving for power, status, and fame, we suppress our true nature, resulting in a false self-image that we perceive as reality. The knowledge of the ancient masters allows us to rediscover the connection between the material and the spiritual. It forms the foundation for the Vedic sciences of Yoga and Ayurveda, which show us how to lead a healthy, authentic, and self-determined life.
