"The oak can develop itself, the lion feels its strength through its nerves, but the human has sunk down to the delusion that nature is too stingy towards him, and had only given him alone no positive powers and no innate growth. The human has like any other creature his peculiar stamp; when he does not blur this, he gets to know nature and himself. But when he loses it, then he can indeed play with words and expressions learnt by rote, but he will obtain no sparks of pure knowledge and truth. The truth of humanity is based on the consciousness of immortality!"
To show how to obtain the consciousness of immortality, Krebs describes by way of examples a form of letter mysticism composed of the concentrated thinking and feeling of letters through the parts of the body.
