I love to plunge deep into the ocean of life; but it is not without losing sometimes all sense of the axis and the pole, without losing myself and feeling the consciousness of my own nature and vocation growing faint and wavering. The whirlwind of the wandering Jew carries me away, tears me from my little familiar enclosure, and makes me behold all the empires of men. In my voluntary abandonment to the generality, the universal, the infinite, my particular _ego_ evaporates like a drop of water in a furnace; it only condenses itself anew at the return of cold, after enthusiasm has died out and the sense of reality has returned. Alternate expansion and condensation, abandonment and recovery of self, the conquest of the world to be pursued on the one side, the deepening of consciousness on the other--such is the play of the inner life, the march of the microcosmic mind, the marriage of the individual soul with the universal soul, the finite with the infinite, whence springs the intellectual progress of man. Other betrothals unite the soul to God, the religious consciousness with the divine; these belong to the history of the will. And what precedes will is feeling, preceded itself by instinct. Man is only what he becomes--profound truth; but he becomes only what he is, truth still more profound. What am I? Terrible question! Problem of predestination, of birth, of liberty, there lies the abyss. And yet one must plunge into it, and I have done so. The prelude of Bach I heard this evening predisposed me to it; it paints the soul tormented and appealing and finally seizing upon God, and possessing itself of peace and the infinite with an all-prevailing fervor and passion.
