Arulmozhi: Pranam Swamiji! Why we cremated human beings only nor other creatures? Somebody says that we should bury the dead bodies, it will become manure for the soil. So they say buried is the best method. Give Scientific reason and Vedic Mantra also.
Swami Ram Swarup: My blessings to you.

We have to follow the vedic path in which first God, vide Yajurved mantra 40/15 state that the human-body must be put on pyre and burnt according to vedic rule. So this also gives us inspiration that if other creatures are dead then suitably to avoid spreading of bad bacteria, their bodies must be burnt and this responsibility rests on government, human beings . It is also known that municipal community discharges its duties in this matter. As per as burial is concerned, several bacteria generate in the body and you know earth has several holes by which the bad bacteria of buried dead bodies come out and harm living beings.

Rajesh Sharma: BRAHMA VISHNU MAHESH KE EK ROOP KA KYA NAAM HE.
Swami Ram Swarup: In this regard, I paste my article below:-

Are Brahma, Vishnu, Mahesh Gods?

Brahma, Vishnu, Mahesh are not God. Vedas tell that there is only one formless God who never takes birth. He creates, nurses and destroys the universe. His power is enough to create and control the whole universe. He is Almighty i.e., He has all unlimited powers and therefore He does not need any assistance to create, nurse and destroy the universe by Brahma, Vishnu, Mahesh. If God needs assistance then He will not be called Almighty. So God does not need any support but we all humans as well as all living beings need His support and blessings every time. However, in Vedas, there are innumerable names of Almighty God according to His divine qualities. So Brahma, Vishnu, Mahesh etc., are also the names of the formless Almighty God. Brahma means the greatest. Vishnu means omnipresent and Mahesh means the greatest.

It is the personal matter of worship or not to worship. So atheists are also there. But it is very clear that God in Vedas as clarified that He Has blessed the human being with human body to worship and realise God. Nobody can attain happy life in the absence of worship of God. One more thing is clear from Vedas in which God states –Oh man/woman you live on the earth given by God and all comforts provided by the God. And if you do not remember/worship God then it is sin and punishment is awarded by the God.

Very few persons know that present science has also come out from Vedas, especially Rigved. The knowledge of Vedas also emanates from God. So, it is clear that scientist also enjoy science which is given by God. God is not only the matter of blind faith. It is the matter of discussion with a learned acharya of Vedas and Yoga philosophy who from Vedas, shastras and Upnishads etc., and scientifically also prove the existence of God. For example- we see the creation and can think deeply that who has created it or is it a job of man/woman, scientist etc., then automatically after long discussion we would reach on the conclusion that men/women/scientist have not created the universe and then He who has created is called Almighty God.

Vishnu is also a name of formless, Almighty God based on quality. Quality is a sunder- “Vishnu” word is made from “Vishlari” Dhatu and the sense of Vishlari” is omnipresent. So he who has the quality of being Omnipresent at all times without a second’s break, He is Vishnu and no other Vishnu exists equivalent to this God. Similarly, Brahma= “Vri Vridhau” i.e., the biggest amongst the universe. Naturally, He is Almighty God. So, the name of Almighty God is also Brahma. Similarly, according to Yajurved mantra 16/41 shiv means he who is beneficial/causes welfare, is shiv. The most beneficial, who creates and nurses the universe is Almighty God. So, Shiv is also name of Almighty God.
