In each age, Vishnu in his form of Vedavyasa, divided the Vedas. In every dvapara yuga, this is done. The present manvantara is the Vaivasvata manvantara and in this manvantara, the Vedas have already been divided twenty-eight times. The names of these twenty-eight Vedavyases were Svayambhu, Prajapati, Ushana, Brihaspati, Savita, Mrityu, Indra, Vashishtha, Sarasvata, Tridhama, Trivrisha, Bharadvaja, Antariksha, Vapri, Trayaruna, Dhananjaya, Kritanjaya, Rinajya, Bharadvaja, Goutama, Haryatma, Vena, Trinavindu, Riksha, Shaktri, Parashara, Jatukarna and Krishna Dvaipayana. The Vishnu Purana says that the next Vedavyasa will be Drona’s son Ashvatthama. As you may know from the Mahabharata, Ashvatthama is immortal.
The essence of brahman and the four Vedas is captured in the word Om. Brahman is everywhere, but appears to different people in different forms.
The four Vedas, Rig, Yajur, Sama, and Atharva, together have one lakh shlokas. It is from the Vedas that the ten famous sacrifices (yajnas) originate. When Krishna Dvaipayana Vedavyasa sought to divide the four Vedas, he first gathered around him four disciples who were learned in the Vedas. Paila was taught the Rig Veda, Vaisham-payana the Yajur Veda, Jaimini the Sama Veda and Sumantu the Atharva Veda. Krishna Dvaipayana taught the Puranas to his discipline Romaharshana.
