What is love? Many poets and writers tried to describe this feeling for centuries. Each time a result was different. It is something so mysterious and elusive, different for every person. Often we use this word without hesitation but if we will look there are so many kinds of love. Mother loves her children. This is disire to take care of children, hug and caress. Children love their mother. This is imitation, admiration, obedience. Old man loves his wife. This is respect, friendship, habit. Young people love each other. Often this is passion and admiration. Dog loves his master. Here we can see faithfulness and friendship. The owner loves the dog. Here we can see protection and friendship. People can love their country. This is respect to culture and traditions, to people, willingness to sacrifice oneself. People can love God. Here we can see self-sacrifice and awe. In each case love is affection but reasons and manifestations are different. Love is not feeling like pain or joy. This is combination of other feelings that we can define. But for simplicity we use this word: "love". Sometimes it's hard to understand yourself, sometimes we are lazy. So love is only a word. Love is an illusion.
