Who is not endued with the same What is he that devours the Sun and what is the Sun? What is Vidya and what is Avidya? What is Vedya and Avedya? What is Immobile and Mobile? What is without beginning, what is indestructible, and what is Destructible? These were the transcendental questions put to me by that foremost of Gandharvas.
