"Does personality survive in the ultimate union with God? If personality means a conscious existence distinct, though not separate, from God, the majority of advanced Moslem mystics say "No!" As the rain-drop absorbed in the ocean is not annihilated but ceases to exist individually, so the disembodied soul becomes indistinguishable from the universal Deity. It is true that when Sufi writers translate mystical union into terms of love and marriage, they do not, indeed they cannot, expunge the notion of personality, but such metaphorical phrases are not necessarily inconsistent with a pantheism which excludes all difference. To be united, here and now, with the World-Soul is the utmost imaginable bliss for souls that love each other on earth. … Strange as it may seem to our Western egoism, the prospect of sharing in the general, impersonal immortality of the human soul kindles in the Sufi an enthusiasm as deep and triumphant as that of the most ardent believer in a personal life continuing beyond the grave. Jalaluddin, after describing the evolution of man in the material world and anticipating his further growth in the spiritual universe, utters a heartfelt prayer — for what? — for self-annihilation in the ocean of the Godhead."
