Unknown

 The enlightened sages possess vast knowledge. They know things about the human body and the structure of the universe that modern medicine and science still do not know. Thousands of years ago, the Rishis described the structures of the atom and sub-atomic particles that modern scientists have only recently discovered. These ancient sages accomplished that without the use of telescopes or microscopes. Their laboratory was their body and their tools were their mind and meditation. They discovered within their own consciousness the home of all knowledge.
