Thus evil, which is merely the negation of the moral beauty of the Reality, appears in the latest emanation as the unreal background which is the inevitable result of a projection of the emanation from the First Cause, who is entirely good, into a world of phenomena. Evil is therefore not real, it is merely the result, the inevitable result, of the mingling of reality with unreality. In fact, this is implied in the doctrine that all other than God is unreal.

On closer examination, however, it does not appear that Buddhist influence can have been very strong, as there are essential differences between Sufi and Buddhist theories. A superficial resemblance exists between the Buddhist nirvana and the fana or re-absorption of the soul in the Divine Spirit of Sufism. But the Buddhist doctrine represents the soul as losing its individuality in the passionless placidity of absolute quiescence, whilst the Sufi doctrine, though also teaching a loss of individuality, regards everlasting life as consisting in the ecstatic contemplation of the Divine Beauty.

As other than God is merely illusive it is obvious that a knowledge of God the Reality cannot be attained by the medium of created things, and thus the Sufis were led, like the neo-Platonists, to attach greater value to immediate intuition by the rational soul than to the use of arguments, and so to place direct revelation above what is ordinarily described as reason. This is a line of development common to all forms of mysticism, and results in a preference for ecstasy or similar spiritual experience above the record of past revelation as given in the Qur'an.
