Pitru Dosh and Jain community

I got introduced to several seekers from the Jain community during my visit to Jodhpur few months ago , all of whom had come to attend the three-day Pravachan and all of them suffered from Pitru Dosh (curse of the ancestors) of a severe level. This makes it clear why Pitru Karma (post-death rituals pertaining to the ancestors) have been accorded so much importance in Sanatan Dharma. And what catastrophe has fallen on the followers of those sects who have not accepted this important component of Sanatan Dharma !-Tanuja Thakur
