I need a translation PLEASE!

Hello i am after the translation for ‘goddess within’ in quenya but happy for it to be in any other type of elvish except black speech.

Would really appreciate your help!

Quenya doesn't have a word for "goddess" proper — the closest match might be Valië, a term for a female Vala, one of ruling angelic powers in Arda. Middle Quenya gives us mitya for "interior," which I think is fine for this sense.

So perhaps mitya Valië "interior Valië," keeping the above in mind.
