One must acknowledge that intelligence holds sway in nature. And if you really study nature, you can find this intelligence holding sway everywhere. And you will then think more humbly about your own intelligence, for first of all, it is not as great as the intelligence ruling in nature, and secondly, it is only like a little bit of water that one has drawn from a lake and put into a water jug. The human being, in fact, is just such a water jug, that has drawn intelligence from nature. Intelligence is everywhere in nature; everything, everywhere is wisdom. A person who ascribes intelligence exclusively to himself is about as clever as someone who declares: You’re saying that there is water out there in the lake or in the brook? Nonsense! There is no water in them. Only in my jug is there any water. The jug created the water. So, the human being thinks that he creates intelligence, whereas he only draws intelligence from the universal sea of intelligence.
