Sharaddh Karma

In the Hindu religion, it is the ritual that one performs to pay homage to one's 'ancestors' (Sanskrit: Pitṛs), especially to one's dead parents. Conceptually, it is a way for people to express heartfelt gratitude and thanks towards their parents and ancestors, for having helped them to be what they are and praying for their peace. It also can be thought of as a "day of remembrance".
