Each kalpa cycle is presided over by a number of Manus, one for each manvantara, and each manvantara has a number of Yuga Cycles, each with four yuga ages of declining virtues. The Hindu view of the universe is that of a cyclic phenomenon that comes into existence and dissolves repeatedly. The Vishnu Purana elaborates on the role of Vyasa in Hindu chronology. Hence he was called Veda Vyasa, or "Splitter of the Vedas," the splitting being a feat that allowed people to understand the divine knowledge of the Veda. Hindus traditionally hold that Vyasa subcategorized the primordial single Veda to produce four parts as a canonical collection. He says that Vyasa being only a title, anyone who composed a new Purana was known by the name Vyasa. Swami Vivekananda expresses the opinion that Vyasa may not have been a single person but a lineage of sages who were content to simply develop the ideas without claiming credit, as they were free from desire for the results of their work, and hence attributed the authorship to Vyasa. The word "Vyasa" ( Vyāsa) refers to "compiler," or, "arranger," and also means "separation," or, "division." Other meanings are "split," "differentiate," or, "describe." It is also a title, given to "a holy sage or a pious learned man," and applied to "persons distinguished for their writings." Vyasa's birth name is Krishna Dvaipayana, which possibly refers to his dark complexion and birthplace, although he is more commonly known as "Veda Vyasa" ( Veda Vyāsa) as he has compiled the single, eternal Veda into four separate books - Rigveda, Samaveda, Yajurveda and Atharvaveda.
