Dear Amit, Do you know who Mahavir or Vardhman was? He was a Hindu or you can say a tribal who did not have a name. Same is for Sidhdhartha later known as Budhdha.
And this very philosophy- DHARMA is not a religion. The English word religion does not define our Dharma. Read Bhagini Nivedita's Book. Today what do you think about BHAKTI ? Is it devotion? If you say yes, you don't know what Bhakti means.
I request you to not to malign our great BHARATIYA DHARMA OR HINDU DHARMA BY just giving it a name and making it narrow. As you might know "BHAGVAD GEETA" our main scripture, does not have a single word called HINDU, it talks about WHOLE MANKIND OR HUMANKIND.
So learn from Mahavir and Budhdha - and start reading BHAGVAD GEETA. which was told by the great incarnation Lord Krishna.
