To understand vijnana, knowledge of the past events or itivrtta, is essential. Seer scientists have divided these events into two categories--purana (ancient legends) and itihasa (historical episodes illustrating and explaining the supraphysical forces and their functioning). The Purana contains the explanation of the Creation. The Itihasa is the compendium of human endeavour. -- Pandit Madhusudan Ojha in Jagadguruvaibhavam (Brahma's Universe: The Chronicle of Creation)
