One I have found myself from a commentary on one Upanishad.
It says the word is derived like this:
Upa (meaning near)+ Nishanna (specially present).
So, "near which, sons, animals-like fruits of Upasanas, are specially present". So, going by this derivation, Upanishad refers to an Upasana or a form of worship.
- What are some other etymological derivations for the word?
Please use only scriptures as references while answering.
NOTE- Although I prefer that the answers should be scripture based but since I am not getting any answers like that I have relaxed the condition a bit. So as to accommodate answers like the one that Pandya has posted.
But I will accept an answer that is based on the scriptures.
