There is one God and one truth, one religion and one mysticism; call it Sufi mysticism, Christian mysticism, Hindu mysticism, Buddhist mysticism, whatever you may. As God cannot be divided, so mysticism cannot be divided.
It is an error when a person says that: My mysticism is different from your mysticism. He has not yet known what mysticism means.
There cannot be many mysticisms; there is one mysticism. There can only be one wisdom. It is the error of mankind that there is Eastern and Western wisdom. As long as Eastern and Western is attached to wisdom, it is not wisdom. If that is passed, he touches wisdom, the
inheritance of mankind.
It is the divine heritage that man has, no matter to what part he belongs. It is also an error when man distinguishes between occultism and mysticism. This error is made by limited man who does not know what he says. The one who wishes to think he knows, he does not know.When a person pictures mysticism as a branch of the tree which is truth, he is mistaken, and when he says that mysticism is a branch and all other things are branches, he is mistaken. Mysticism is the stem to which all others are attached.
Nowcoming to the question, what really mysticism is. Mysticism is the way by which to realize the truth.
