Vyaasa classified the huge body of literature of Vedas into four parts and hence he got the name "Veda Vyaasa" (वेदव्यास / ವೇದವ್ಯಾಸ). Veda Vyaasa, being a great guru in our tradition was a great reservoir of knowledge. He composed the essential message of the vedas in the language of the commoners as Mahabharata (महाभारत / ಮಹಾಭಾರತ), Bhaagavata (भागवत / ಭಾಗವತ) , and other 18 puraanas (पुराण / ಪುರಾಣ) . He taught all this to Sumanta (सुमन्त / ಸುಮಂತ), Jaimini (जैमिनि / ಜೈಮಿನಿ), Vaishampaayana (वैशम्पायण / ವೈಶಂಪಾಯಣ), Shuka (शुक / ಶುಕ) and others who preserved it by teaching others. He was born to Satyavati and Paraashara in an island of the Yamuna river. One has to remember this great guru for the protection of the knowledge learnt.
