Bharatiya culture says that, just as we serve our parents and close relatives when they are alive as part of abiding by ourDharma, we have certain duties unto them after their death. The shraddha rites provide us with an excellent opportunity to fulfil these duties and repay our debts unto the pitars (ancestors). The shraddha rites are necessary so that the journey after death of our parents, who have taken our utmost care during our childhood, becomes comfortable and without any distress, and that they acquire sadgati (Momentum for moving to the next higher region).
If shraddha is not performed, the desires of the pitars (Deceased ancestors) remain unfulfilled. Negative energies make easy victims of such desire-riddled pitars and then, enslave them. Shraddha, Sanskrit śrāddha, also spelled sraddha, in Hinduism, a ceremony performed in honour of a dead ancestor. The rite is both a social and a religious responsibility enjoined on all male Hindus (with the exception of some sannyasis, or ascetics). The importance given in India to the birth of sons reflects the need to ensure that there will be a male descendant to perform the shraddha ceremony after one’s death.
