Love is important for life. But not in the sense that one will die if he does not receive love from that someone special. This kind of love is very selfish and materialistic. Love should be pure and unselfish. It should be a bonded relationship and not mere physical attraction. Love is in many forms. Between parents and children, between siblings and between bonded couples and even the relationship between God and devotees are all love. These relationships are needed in everyone's life for his living happily. If he does not get at least one of these kinds of love, it is very difficult to live. So, I say man needs love just like food and shelter.
