Only a loving person is able to understand another person and accept him as he is, with all the advantages and disadvantages. Love is considered one of the components of human socialization and is characteristic only of homo sapiens - it is quite likely that it was the ability to love, rather than work, from the "human monkey". Without love, a person can not understand others and himself, find a place in this world, get pleasure from life. This is an unhappy man, devoid of the main joy of life. And only a person who loves can know life in all its glory, feel all the fullness of feelings that can be experienced in relation to another person.
After reading your article, I understand that Love stands apart from other human feelings, differing from them by its spirituality, sublimity, motivation for creation and self-improvement. One of the main "symptoms" of love - when a person gets more pleasure from what he gives, than from what he receives, while not demanding anything in return. We are not talking about material things, but about spiritual things-roughly speaking, loving, we give our lives to man, because from now on all thoughts, all joys and sorrows are connected with the beloved person.
