To an elucidation of this system, and the technical terms employed there in, the following pages are devoted; but to avoid breaking the continuity of the account, I have endeavoured to present an epitome of the Oriental Mysticism Philosophy from the point of view taken by the Mohammedan writers, from whom my information is chiefly derived. Mystic meaning is popularly known as becoming one with God or the Absolute, but may refer to any kind of ecstasy or altered state of consciousness which is given a religious or spiritual meaning. It may also refer to the attainment of insight in ultimate or hidden truths, and to human transformation supported by various practices and experiences I must therefore premise that any dogmatical statements that may occur in the course of the work are not to be considered as enunciation of my own opinion, but as an exposition of the views of those whose system I am attempting to expound.
