What is love on a universal scale?

Love is the creative force of the universe. The Creator of All That Is is the definition of pure love and light. We all come from the creator and so we are beings of love. We just forget that too often and so we create our little dramas here on this planet. There is only love and unity. All the rest is all an illusion.

A complicated relationship between the lingering tribe mentality and the biochemical reaction which triggers desire and the need to mate. On a universal scale there is no such thing. Love is a construct used to explain in simplistic terms the explanation above.

the feeling of one:

Wanting another person being close to one, near to, be together

Wanting to be seeing, hearing, ...

Feeling kind/dear to that person

Wishing good for that person

Wishing good (no bad) to happen to that person,

Wanting not to be departed from, separated from

This feeling is called in one word: Love.

A minor
