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.
I sit on the front porch of our cabin and "listen" to the complete silence. It's so quiet that when a bird flies past, I can hear the air passing beneath its wings. Gradually I become one with the silence and my heart opens to the joy of life. During the winter, when we don't live at the cabin, I visualize sitting on that porch as a way to "stop" the hustle and bustle of my day-to-day world.
