Above all, do not lose your desire to walk. Everyday, I walk myself into a state of well-being & walk away from every illness. I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it. But by sitting still, & the more one sits still, the closer one comes to feeling ill. Thus if one just keeps on walking, everything will be all right.

The spiritual differs from the religious in being able to endure isolation. The rank of a spiritual person is proportionate to his strength for enduring isolation, whereas we religious people are constantly in need of 'the others,' the herd. We religious folks die, or despair, if we are not reassured by being in the assembly, of the same opinion as the congregation, and so on. But the Christianity of the New Testament is precisely related to the isolation of the spiritual man.

The deepest form of despair is to choose to be another than himself.

If anyone proposes to believe, i.e., imagines himself to believe, because many good and upright people living here on the hill have believed, i.e., have said that they believedthen he is a fool, and it is essentially indifferent whether he believes on account of his own and perhaps a widely held opinion about what good and upright people believe, or believes a Münchhausen.

Irony is the cultivation of the spirit and therefore follows next after immediacy; then comes the ethicist, then the humourist, then the religious person.
