Many people also observe the day as "Vyasa Purnima," remembering the sage Ved Vyasa, who penned the Hindu epic Mahabharata and the Puranas, on his birthday.
The Vedas are thought to have been organised by the sage and divided into four sections: Rig, Yajur, Sama, and Atharva. He was born on this day to Satyavati and the Brahmin sage Parashar, and according to Hindu mythology, he is one of the seven immortals who still wander the earth.
