In love abides all knowledge. It is mankind's love and interest in things that in time reveals their secret, and then man knows how to develop, control, and utilize them. No one can know anybody, however much he may profess to know, except the lover, because in the absence of love the inner eyes are blind. Only the outer eyes are open, which are merely the spectacles of the inner eyes. If the sight is not keen, of what use are the spectacles? It is for this reason that we admire all those whom we love, and are blind to the good qualities of those whom we do not love. It is not always that these deserve our neglect, but our eyes, without love, cannot see their goodness. Those whom we love may have bad points too, but as love sees beauty, so we see that alone in them. Intelligence itself in its next step towards manifestation is love. When the light of love has been lit, the heart becomes transparent, so that the intelligence of the soul can see through it. But until the heart is kindled by the flame of love, the intelligence, which is constantly yearning to experience life on the surface, is groping in the dark.
