47. Divine love and wisdom cannot fail to be and to be manifested in others that it has created. The hallmark of love is not loving ourselves but loving others and being united to them through love. The hallmark of love is also being loved by others because this is how we are united. Truly, the essence of all love is to be found in union, in the life of love that we call joy, delight, pleasure, sweetness, blessedness, contentment, and happiness.

The essence of love is that what is ours should belong to someone else. Feeling the joy of someone else as joy within ourselves--that is loving. Feeling our joy in others, though, and not theirs in ourselves is not loving. That is loving ourselves, while the former is loving our neighbor. These two kinds of love are exact opposites. True, they both unite us; and it does not seem as though loving what belongs to us, or loving ourselves in the other, is divisive. Yet it is so divisive that to the extent that we love others in this way we later harbor hatred for them. Step by step our union with them dissolves, and the love becomes hatred of corresponding intensity.

89. Warmth and light emanates from the sun that arises from divine love and wisdom. In the spiritual world where angels and spirits live, there is just as much warmth and light as there is in the physical world where we live. The warmth feels just like warmth and the light looks just like light, as well. Still, the warmth and light of the spiritual world and the warmth and light of the physical world are so different that they have nothing in common, as I have already mentioned [83]. They are as different as life and death. The warmth of the spiritual world is essentially alive, and so is the light; while the warmth of the physical world is essentially dead, and so is the light. The warmth and the light of the spiritual world come from a sun that is nothing but love, while the warmth and light of the physical world come from a sun that is nothing but fire. Love is alive, and divine love is life itself. Fire is dead, and solar fire is death itself. We may call it that because it has absolutely no life in it.
