In the vast cosmic exchanges the universal life goes and comes in unknown quantities, rolling entirely in the invisible mystery of effluvia, employing everything, not losing a single dream, not a single slumber, sowing an animalcule here, crumbling to bits a planet there, oscillating and winding, making of light a force and of thought an element, disseminated and invisible, dissolving all, except that geometrical point, the I; bringing everything back to the soul-atom; expanding everything in God, entangling all activity, from summit to base, in the obscurity of a dizzy mechanism, attaching the flight of an insect to the movement of the earth, subordinating, who knows?

在宇宙广袤无边的运动中，无量数的空间活动交相往来，把一切都卷进那神秘无形的散漫中，并也利用一切，即使是任何一次睡眠中的任何一场梦也不放弃，在这儿播下一个微生物，在那里撒上一个星球，摇摆，蛇行，把一点光化为力量，把一念变成原质，散布八方而浑然一体，分解一切，而我，几何学上的这一点，独成例外；把一切都引回到原子棗灵魂，使一切都在上帝的心中放出异彩；把一切活动，从最高的到最低的，交织在一种惊心动魄的机械的黑暗中，把一只昆虫的飞行系在地球的运转上，把彗星在天空的移动附属于棗谁知道？
