What is Pitri-Rina ? How to get rid of it ? What are the details about Pitri-Rina ?
Many people say that having a son is mandatory to get rid of Pitri-Rina. But in modern history lots of people who were highly spiritual persons remained unmarried eg- Adi Shankaracharya . I think many of the present Shankaracharya are also unmarried. Most spiritual persons now a days don't marry . And I am sure they must be well versed in the scriptures . Why don't they get married ?
Was this rule of having a son not applicable in Kaliyuga ?
Because upto Dwapar Yuga ,world was completely different from Kaliyug. People would literally see their ancestors in heaven. Visits of gods like Indra was normal. World was completely different from now.
