Sanskrit scripture (4)
I believe the answer is:
veda
'sanskrit scripture' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for veda that I've seen before include "Most ancient and sacred literature of Hindus" , "Sacred text of Hinduism" , "Ancient Hindu scripture" , "Sacred literature of Hindus - asks Dave" , "Hindu scriptures" .)
