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.
Meditation is basically the practice of quieting the mind on deeper and deeper levels until we reach the underlying, subtle consciousness that is the root of all things. But a quiet mind does not mean the absence of thoughts. It means a mind that does not interfere with or distort the natural flow of sensations, feelings, perceptions, images, and thoughts through the open field of our consciousness. A quiet mind is a clear space, a mirror for the entire experience of inner and outer life.
