Chitra Pournami, or Chitirai Purnima, is a unique Tamil festival observed on the full moon day (Poornima) in the month of Chitirai. In 2017, the date of Chitirai Pournami is May 10. The day is dedicated to Chitragupta, the official keeper of deeds in the abode of Yama. It is believed that bathing in holy rivers and temple ponds on the day will wash away the sins committed. In Hinduism, Chitragupta, the first assistant of Lord Yama, is the one who keeps record of the good and bad deeds of human beings on earth. After death, when one reaches the abode of yama, it is he who tallies the good and bad deeds and declares it to Yama. Therefore, the day is dedicated to Chitragupta and devotees pray to him to forgive their sins. Another important legend associated with Chitra Poornima, involves Lord Indra, the king of Gods, and his Guru Brihaspati. Once Indra and Brihaspati had an altercation, and the Guru stopped advising his pupil. Without the sound counsel of his Guru, Indra committed numerous sins.
