I believe the answer is:

yajur veda

I'm a little stuck... Click here to teach me more about this clue!

'terrible energy-filled vajrayudha cut devilish vritra's feet in this ancient indian' is the definition.
The definition suggests a singular noun which matches the answer.

'text' is the wordplay.
I cannot really understand how this works, but
'text' could be 'veda' (I have seen 'Sacred text' mean 'veda' so perhaps 'text' could also mean 'veda') and 'veda' is present in the answer.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

I've seen this clue in The Hindu.
