Know the Rishis and Rishikas, the early creations and their descendents, the wise men and women of the unknown and unfathomable eons, that were the embodiments of knowledge and sublimity, purity and humanity and compassion and humility. They were great scientists, discoverers, and research guides; and inventors of food-grain to fruits and flowers; of ploughs and yoke to Ayurveda and herbal medicines; from boats and ships to road-transports and planes; of everything that we possess today, from celestial bodies to metaphysics, geometry, trigonometry, algebra and photography, and numerous other things. We are proud of them and their gifts. Know the Rishis and Rishikas that knew and taught all about the earth and universe; planets and constellation; climate, seasons and meteorology, clouds, rain, water, fire, space and soil. They gave us the ways of constructing huts and ashramas to temples and palaces, and made us know the physical body and spiritual self, the outer reality and the inner truth, and taught us the ways of health, wealth, peace, pleasure and prosperity.
