its when you love someone so much you feel ''high'' in a way ^^

True love can be anything, you have to feel it rather than the explaination by words. The most commonly true love that you can feel are the relations between mother-children, husband-wife, perhaps boyfriend - girlfriend.

True love is the merging of two souls as well as two bodies.

"True love" can be a difficult concept to define. It is a highly subjective term. However, generally speaking, this is the definition most associated with cultural references to the term: True love: Noun 1. (uncountable) The form of romantic affection that is considered pure and wholly positive, not just based on feelings of lust. 2. (countable) The unique individual for whom one feels such affection.
