I am a brahmana and I have eaten beef and also consumed alcohol sometimes with knowledge, sometimes without due to friendship of so called neo-secularist, Marxists, modern thinkers etc…… Around six months back, I realized the my mistake and stopped consumption of alcohol, eating all kind of non-vegetarian including eggs. Recently one of my friend told me I also need to do “prayashit “ for what I have done. Can anyone tell me ways to do prayashit for above said sins?
