Purity: Take a bath (preferably in the Ganga) before the ritual. Wear clean, simple clothes (often white dhoti for men, simple saree for women; new unwashe,d clothes are sometimes specified for rituals like Tripindi Shradh).
Diet: Maintain a simple vegetarian (Sattvic) diet on the day of Shradh. Avoid non-vegetarian food, onion, garlic, alcohol, etc., during the Pitru Paksha period if possible, or at least on the day of the ritual. Some observe fasting until the ritual is complete.
Conduct: Maintain a solemn, respectful, and devotional attitude throughout. Avoid arguments or negative thoughts.
Hygiene: Traditionally, shaving and haircuts are avoided during Pitru Paksha until the Shradh is completed.
Family Participation: Ideally, the eldest son performs the rites, but other male members can participate. In the absence of male heirs, women can also perform Shradh.
