We need to distinguish between feel good tame biological light like humour that may be moist and harsh radioactive light that might hurt a biological entity or kill it.  John Dowland gave the first reference to tame light in his lute music lyrics.
Fermat arguably is very famous for his jurisprudence and his path integral of least time.  He may actually be the father of quantum mechanics because of his path integral.
Feynmean updated it and created the path integral of least action whcih actually works with harsh light.  Feynman died of cancer.
The path of least gravity and least time might actually be best very often.
Ultimately in the far future,  the path of least entropy and most negative entropy might be the most intelligent path for consious living light but that might be a bit greedy!
food for thought.
and what about the path of least harsh light and best sound or best smell, or best touch or best taste.and best feeling and best thought.. and is this realistic or true or purely imaginary.
I suggest you ask the Dalai Lama what conscious living light is!  Have you heard about the way they remove gall stones and kidney stones by chanting! ultrasonics

consious living light.

What is that?
