Narayan Nagbali consists of two different rituals. Narayan bali is done to get rid of ancestral curse (pitru dosh /Pitru Shaap) while Nag bali is done to get rid of sin performed by killing snake, specially Cobra which is worshipped in India. It can be performed only at Trimbakeshwar.

Narayan Bali ritual is done to fulfill the unsatisfied desires of the ancestral souls which are stuck in the world and trouble their progeny. Narayan Bali consists of the same ritual as Hindu funeral. An artificial body mostly made of wheat flour is used. Mantras are used to invoke such souls who are having certain wishes remaining attached. The ritual makes them possess the body and the funeral frees them to the other world.

Nagbali ritual is done to get rid of sin of killing nag (Cobra). In this ritual also the funeral is performed on the body of snake made with wheat though.
Narayan Nagbali is one of the main rituals performed at Trimbakeshwar.

Ancient scriptures like Dharma Sindhu, which describes various religious rites, mentions that this particular ritual should be done only at Trimbakeshwar. The references are found even in Skandh Puran and Padma Puran about this age-old tradition.

In modern era, the means of "Test tube baby” are available. Even though the couple does not afford, they get the necessary treatment, sometimes even by getting money on loan.

But when they do not get any positive response of all modern treatment, they turn the astrologers in frustration. The astrologers can only analyze the reasons of failure of all medical treatments. After carefully examining the sex organs of both, if it is found that there is no fault in anybody and still there is no chance of issue, astrologers can only reply this question. Always when there is deceased, there must be some remedy also.
