QUOTE : Accordingly, the loss of the beloved one through a rival, or through death, is the greatest pain of all to those passionately in love; just because it is of a transcendental nature, since it affects him not merely as an individual, but also assails him in his essentia aeterna, in the life of the species, in whose special will and service he was here called. This is why jealousy is so tormenting and bitter, and the giving up of the loved one the greatest of all sacrifices.
