Ajay: Swami ji parnam..I have confusion related yag. As we are Hindu, so we people prefer to do yag and all because as we have heard that yag is beneficial for us so we have to do on daily basis..but if we talk about Muslim , Sikh or Christian then they people do not prefer to do yag. So according to them yag is nowhere in their life. So my question is why only Hindu people do yag? Why not other religion like Muslim, Sikh and Christian?
Swami Ram Swarup: My blessings to you my son. Actually India is situated at the bank of river Sindhu so in the past the foreigners started saying us Sindhu then Indu and then Hindu. So the Hindu word has been given to us by the foreigners. But now we are proud of being Hindu. Otherwise the fact is this we the Indians are arya.

Secondly in the beginning of the creation of the universe when non-sexual living beings are created then the present sects did not originated/made. Therefore the knowledge of Vedas which emanates direct from God is made applicable for the all human beings and infact it is at present is equally applicable for all human-beings.

So as per Vedas Yajyen is universally applicable for all human beings because Vedas further says that when Yajyen is performed it becomes beneficial for not only human beings but is beneficial for living beings and even for all non-alive universal matters.

So when learned person organize Yajyen he knows that he is giving benefit to whole of the universe say Vedas. Always love all living beings and universal matters. They prefer humanity.
