Is the supreme court is a religious body to decide what is religion. Please keep in mind Buddism was a wide spread religion in India. why did it disappear altogather from India. Its because of the revival of Hinduism. So Buddhism was treated as a religion and was eliminated.
Please note that we have high dose of secularism, we lack a clear understanding of our own religion. Truly we are not practicing our religion in a true sense nor those Judges and hence we cannot conclude that Hinduism is a way life and not a religion.
