*Meaning of the mantra: Salutations to the ancestors, salutations to the god-like rs'is. (Those who, by inventing new things, have broadened the path of progress of human society, are known as rs'is.)
The act of offering is Brahma; that which is offered is Brahma; the One to whom the offering is made is Brahma; and the person making the offering is Brahma.
One will merge in Brahma after completing the duty assigned to him/her by Brahma.
Repeat the mantra together with the mudra' three times.
Remembering the rs'is and ancestors in this way is known as Pitr Yajina. Pitr Yajina should be performed as a daily duty even if one's father is alive.
