Shraddh Ceremoney
On each day of the dark fortnight (Pitra Paksha), special offerings are made to the ancestors whose lunar date (Tithi) of death corresponds to that particular day. Favourite food items of the departed person are specially prepared and offered after performing a puja .
One must offer food to Brahmin and donate Yatha Shakti. A small portion of the food is also offered to the Cow (Gow Grass) before offering it to Brahmin..
A small portion of the food is also offered to the crow who is considered as a connection between the world of the living and the world of the dead. Round balls of rice and flour, called pinda , are also offered, along with the sacred kusha grass and flowers, amidst sprinkling of water and chanting of mantras from the Sam Veda.
On the day of the shraddh, the souls of dead relatives are invoked. According to matsya puran, these souls are identified with vasu, rudra and adityas who are the shraddh deities. the food offered to the Brahmins on the day of the shraddh and the oblations offered to the sacrificial fire by uttering the name and gotra (clan name) of the dead relative, is transformed by the power of the mantras (sacred hymns) into food appropriate for their present bodies. agni, vasus and the rudras act as celestial messengers and take this food to the respective souls. The ancestors then bless the performer of the shraddh with health, wealth and prosperity.
What customs should one observe during pitru paksha.
