Life force

I have started a thread in which I ask how Quenya might translate the idea of life force when not referring to a spirit. The following will give you an idea of what I am trying to translate.

Raise yourself, you have not died.

Your life force will dwell with you forever.

Well there are words like easte or nasse which sort of come close, but I would rather get quite literal and coin a word *coimelehte "lit. life-force" from coi- "life-" and melehte "might, power (inherent)".
