There are no limits on true self-giving. It is not just to those one likes that one makes the offering. This involves a love that issues from the very CENTER of the person's being, directed to the CENTER of the other person's being, a love that gives ALL that the person is in order to foster the other person's life, a love that is offered to EVERYONE, without exception and without condition. The love is not offered to people because they are one's friends; people become "friends" because one loves them.
We say we aren't listening to ourselves in the name of consideration for others. But this is a false premise because we can't really listen to others until we learn to listen, exquisitely listen, and TO ABIDE by our own heart.
