Love is the principle of action, not a quality of behavior. We cannot learn unconditional love. To love unconditionally, we must become Love. And love is the natural outcome of union with the Inner Self or Soul.
As Aldous Huxley wrote: "There isn't any formula or method. You learn by loving." But sometimes, if we're lucky, we live long enough to grow into it in such a way that because of it we come to recognize the value of life. . . . We learn enough about love to allow things to slip away and ourselves to melt into the God whose love made all of it possible. . . . Sometimes we live long enough to see the face of God in another. Then, in that case, we have loved.
