Psalmów 2:7 Kabała: Zohar, Ohr Ne'erav, The Wars & Pardes Rimmonim

Not that they thereby forfeit any of the bliss which they enjoyed before, since it says “if he take unto him another, her food, etc.” Still, when they ascend into the higher Paradise they remove these garments and are clothed only in their own radiance, for there no garb is worn.’

The same problem arises even when the widow does not marry again. What becomes of her husband’s spirit which cleaves to her? All this must now be explained. Old man, old man!

May I thus cleave to Thee for ever and not be forgotten of Thee.” “For love is strong as death”-as the strength of the region where death dwells is the place called “eternal love”. “Her coals are coals of fire.” What are these coals? The diamonds and precious gems which are born of that fire.
