What is the difference between Tarpan and Pind Daan in Gaya Are they always done together?

• Tarpan: Offering of water (with sesame seeds, etc.) to satisfy the thirst of ancestors. It’s a libation.
• Pind Daan: Offering of Pindas (rounded balls of rice/barley flour mixed with ghee, honey, milk, sesame) representing the physical body, to nourish the ancestors.

While distinct, Tarpan is an integral and mandatory part of the larger Shraddha and Pind Daan ceremony performed in Gaya. Pind Daan is considered incomplete without Tarpan. They are almost always performed together during the main ancestral rites in Gaya
