A common but wrong idea, into which some writers on mysticism fall, is that the final goal is realized by becoming one with the universe--a part of and united with Nature. That is indeed a state which often arises either on the way to the goal or on the return from it, but it is certainly not the ultimate goal itself. Man's highest source is in the infinite fullness of being whereas Nature is an expression of that being just as he is. It is the lesser thing, not the Ultimate Fact. The mystic's true goal must lie beyond it.
