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.
For, there is a Mystery that many call God, manifesting as Universal Love, a set of Laws and a Great Process. That Process works through each and all of us, and that Process is perfect. As we discover this fundamental truth in the journey of our loves, we find that wherever we step, the path appears beneath our feet.
