Vedic Yoga, Path of the Rishis. David Frawly

A true Yoga of nature must employ the language of nature, which resides far from our ordinary forms of human discourse. What is the language of nature? It is not our language of abstract concepts, personal discourse, or dictionary-defined words. It is not the language of science or art, though these may touch upon aspects of what nature may be. The language of nature is first of all the language of light. Light is the presence of cosmic intelligence and carries the visible world on its hidden screen. The pattern of light is a pattern of intelligence working for the unfoldment of all life. Light in its subjective action is consciousness or the seer. In its objective action, light creates the forms of the outer world or the seen.
