When families enquire about Tripindi Shraddha
Families most often ask about it when annual shraddha has not been performed for some years, or on the advice of a priest when they feel ancestral rites remain incomplete. The purohit will listen to your situation before recommending it.
How it is usually performed
In common practice, the three pindas — traditionally of rice, barley and sesame — are offered with worship of Brahma, Vishnu and Shiva, together with tarpan and the associated shraddha rites. The purohit sets the exact sequence according to your family tradition.
