It is said that the language sanskrit is derived from Vedas, i.e. mantras were first revealed to Rishis in deep meditation and then Sanskrit language came from it.
But we also know that Sanskrit is the language of Gods. So how was communication taking place in heaven and other realms or for that matter between Brahma-Vishnu-Shiva before Sanskrit came into form we know today.
There are some who are of the view that Sanskrit was being spoken in other realms before it was revealed to Rishis. That may not be true as "manasputras" preceded devtas. But then for a moment ignore this, accept that Sanskrit was being spoken in heaven and other lokas, and take a step back.
Even Lord Brahma got the Vedas in meditation. He didn't author it. So are we saying vedas were revealed to Lord Brahma who explained it to beings in other realms and in the process Sanskrit language was developed ?
