Many people say that Hinduism believes that we take only one birth and after that way go to heaven or hell. As example -
- In Vedas , there is no mention that we take multiple births. Vedas indicate that we take only one birth.
- Rituals like offering Pind daan to ancestors indicate that our ancestors are still in the heaven or hell.
- In gita Arjun says to Krishna that ancestors of famlies whose varna dharma get destroyed fall from heaven to hell and they resides in hell for eternity.
Hybrid castes ensure that the family line and those who destroyed the family line, both go to hell. Because their ancestors fall and are deprived of offerings of funereal cakes and drink
O Janardana! If the family dharma is destroyed, those men are doomed to spend an eternity in hell. So we have heard.
- Also It is being said that sins and virtues done by people are sometimes borne by the descendants of people who committed sins or virtues. Thus it also indicates no next birth.
Many say that the belief about taking multiple births was added latter by people who didn't understood the scriptures properly. Because scriptures were not in written form but only in the memory of people. So, some people later changed the scriptures.
Also people claiming to remember previous lives doesn't prove that it was their previous birth . As It can be a case of transfer of memory also. There lives a boy (https://www.youtube.com/watch?v=nhGX1YCsvAM) who claimed to remember his multiple previous lives and many of those people (i.e. his claimed previous lives) lived simultaneously. So it is clearly a transfer of memory thing going here rather than previous lives.
