Fatigue & what is "Real"

Chapter 30

At any rate, you will soon find that the justice of Hell is purely realistic, and concerned only with results. Bring us back food, or be food yourself.
Whatever he says, let his inner resolution be not to bear whatever comes to him, but to bear it "for a reasonable period" - and let the reasonable period be shorter than the trial is likely to last.
The general rule which we have now pretty well established among them is that in all experiences which can make them happier or better only the physical facts are "real" while the spiritual elements are "subjective"; in all experiences which can discourage or corrupt them the spiritual elements are the main reality and to ignore them is to be an escapist.
