The liking is only conditional. Similarly, in your case also, if they behave in a strange manner, you would not like to see them. The love of parents and son and daughter, husband and wife, is a conditioned, perishable longing. Nothing can survive in this world except the soul, because that is the character of universality. Other things in the world, any friendships you have, are perishable because they are located in the body only.
Every love is perishable, because it is connected with the body of a person.
But, if it is a love born of the soul, it will have a universal tendency, and it is a love of soul by soul, which is difficult to conceive. Everything has a soul, but you must recognise the soul in it. You should not see that which is covering it. You are talking to the intention, the wish, the longing, the aspiration, the operation of the mind of the person. You are not loving the body of the person.
