Each thing that exists remains forever, and that very existence of existence is proof of its eternity. But without that realization, which is the knowledge of perfect being, man would never know whether there was existence or non-existence. If eternal existence is altered, then it must become more beautiful; and if it disappears, it must return with more sublime image; and if it sleeps, it must dream of a better awakening, for it is ever greater upon its rebirth.
Khalil GibranWhen you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight.
