The furthest stage in development is the Nafs-e-Salima, in which man's consciousness is removed to an abstract plane. In the heart of a man at this point of evolution, love is raised from admiration to worship; his love is part of his being, and his passion, which is never expressed except in the intensity of love, may be compared to the alighting of a bird on earth to pick up a grain of corn. This man lives on a higher plane of life, judging by different standards, though his inspiration springs from the common life of existence. Thinker, visionary, or man of action, he becomes absorbed in the contemplation of the essence of things. He alone becomes unable to regard anything as common or unclean; although in his contemplation of the mystery of life, his devotion to the pursuit of truth, and his self-sacrifice to the cause of humanity, he may become gradually etherealized above every material object. Having reached this point he is truly justified if he should strike the path of celibacy.
