Tarpan
In the memory of their ancestors Hindus offer religious offerings of water called Tarpan during Pitr-Paksha. These offerings are made to the Gods, Rishis, Devas, and especially to one’s ancestors. “Tarpan” is offered during all 15 days in Pitr-Paksha. As this rite is very religious and has specific significance thus, there is a fixed manner to offer Tarpan, which as follows:
Pitr Paksha

* In a dish of half filled water add some milk, sugar, honey, a few grains of barley, a few drops of ghee, and flowers petals
* Now face east and keep 3 pieces of Kush grass across both palms forming a cup and offer this water in the dish – NOT on the ground – in the name of as many deities as possible.
* Then face north and offer water in the name of the Rishis
* Then face south and now add till (Sesame seeds) into the water and offer this in the name of the Pitrs (forefathers).
* Only after all offerings have been completed then the dish of water is dropped on a plant.
* This can be repeated as many days as one desires in the 15 days.
