Hindu literature also states that, "Shradh" work is very important and compulsory duty of human being in the "Pitra-Paksh". Our forefathers visit their family members so sandal, milk, barley, flowers, til, etc, should be mixed with water to pay tribute to our ancestors.¬† "Tarpan" is done on a particular date when our ancestors died. Those who do not remember the death date of their Ancestors, they can do "Shradh" on "Aswhin Krishna-Paksh Amavasya" means "Sarva-Pitra Moksh Amavasya",¬†so that their Ancestors will achieve salvation.¬†On the ninth date of "Pitra-Paksha" which is called "Matra-Navmi", "Shradh" are for the married women.
So if it is possible, offer prayer to your Ancestors with rice, sweet, sandal, barley, til, flowers and water¬†daily during the "Pitra-Paksh".
It is told that, during the "Pitra-Paksh" we recite the name of our Ancestors and whatever¬†we tribute to them, they get that according to the¬†"Yoni" they are in. If, they are in "Pitra-Yoni" then it is in the form of "Micro-Liquid", in "Heaven" it is in the form of "Amrit", in the "Gandharav-Lok" it is in the form of "Bogh", in¬†"Animal-Yoni" it is in the form of "Fodder", in the¬† "Sarp-Yoni" it is in the form of "Air", in "Yaksha-Yoni" it is in the form of "Water",¬†in "Devil-Yoni" it is in the form of "Meet", in "Evil Spirit-Yoni" it is in the form of "Blood", and when the "Pitra" are in the¬†"Human-Yoni" they get it as food and money.
