How can I do a pilgrimage for a deceased parent?
common choices are immersing the ashes at a holy river, piṇḍa-dāna at Gayā, or visiting a tīrtha they loved and giving charity in their name.
Many families first carry the ashes (asthi) for immersion at Haridvār, Prayāgrāj or Kāśī, or at a holy river or the sea near home. At Haridvār and Prayāgrāj, family priests (paṇḍās) often keep genealogy registers going back generations, and they will record the name and perform the immersion rites.
Later — often within the first year or after it — many go to Gayā for piṇḍa-dāna, or perform śrāddha at Badrīnāth's Brahma Kapāl, Nāsik, Puṣkar or the tīrtha of their tradition. Another loving option is to visit a temple your parent was devoted to, take their photo, offer a lamp or abhiṣeka in their name, and feed people there.
Go in a spirit of gratitude, not obligation. Take a trusted priest's guidance for the rites, agree on fees beforehand, and remember that your daily remembrance at home is equally precious. If your situation is specific, Ask Chiluka.
