Krishna Dvaipayana is a respected sage who is depicted in almost all Hindu traditions. He is widely recognized as the author of the epic Mahabharata. Many Hindus consider Vyasa to be a partial incarnation of the god Vishnu and the compiler of the Vedic mantras into four Vedas, as well as the author of the eighteen Puranas and the Brahma Sutras. He is one of Chiranjeevis' eight immortals, meaning that he is still alive in the current Kali yuga. Vyasa's birth name is Krishna Dvaipayana, which may refer to his dark skin and birthplace, but he is better known as "Veda Vyasa" (Veda Vysa) because he divided the single, everlasting Veda into four independent books: Rigveda, Samaveda, Yajurveda, and Atharvaveda. The term "Vyasa" (Vysa) indicates "compiler" or "arranger" and also "separation" or "division." Other definitions include "split", "differentiate", and "describe." It is additionally a term bestowed upon "a holy sage or a pious educated man," in addition to "persons distinguished for their writings." Swami Vivekananda believes that Vyasa was a lineage of sages who were satisfied to simply develop ideas without claiming credit since they were free of desire for the consequences of their work, and hence assigned authorship to Vyasa.
