Hiranyakasipu, the demon who by force enjoyed all the offerings of the sraddha ceremonies performed by our sons and grandsons on the anniversaries of our death and who drank the water with sesame seeds offered in holy places of pilgrimage
SB Canto 7
The inhabitants of Pitṛloka prayed: Let us offer our respectful obeisances unto Lord Nṛsiṁha-deva, the maintainer of the religious principles of the universe. He has killed Hiraṇyakaśipu, the demon who by force enjoyed all the offerings of the śrāddha ceremonies performed by our sons and grandsons on the anniversaries of our death and who drank the water with sesame seeds offered in holy places of pilgrimage. By killing this demon, O Lord, You have taken back all this stolen property from his abdomen by piercing it with Your nails. We therefore wish to offer our respectful obeisances unto You.
It is the duty of all householders to offer food grains to all their departed forefathers, but during the time of Hiraṇyakaśipu this process was stopped; no one would offer śrāddha oblations of food grains to the forefathers with great respect. Thus when there is a demoniac rule, everything concerning the Vedic principles is turned upside down, all the religious ceremonies of yajña are stopped, the resources meant to be spent for yajña are taken away by the demoniac government, everything becomes chaotic, and consequently the entire world becomes hell itself. When the demons are killed by the presence of Nṛsiṁha-deva, everyone feels comfortable, irrespective of the planet upon which he lives.
