“There is an old Eastern fable about a traveler who is taken unawares on the steppes by a ferocious wild animal. In order to escape the beast the traveler hides in an empty well, but at the bottom of the well he sees a dragon with its jaws open, ready to devour him. The poor fellow does not dare to climb out because he is afraid of being eaten by the rapacious beast, neither does he dare drop to the bottom of the well for fear of being eaten by the dragon. So he seizes hold of a branch of a bush that is growing in the crevices of the well and clings on to it. His arms grow weak and he knows that he will soon have to resign himself to the death that awaits him on either side. Yet he still clings on, and while he is holding on to the branch he looks around and sees that two mice, one black and one white, are steadily working their way round the bush he is hanging from, gnawing away at it. Sooner or later they will eat through it and the branch will snap, and he will fall into the jaws of the dragon. The traveler sees this and knows that he will inevitably perish. But while he is still hanging there he sees some drops of honey on the leaves of the bush, stretches out his tongue and licks them. In the same way I am clinging to the tree of life, knowing full well that the dragon of death inevitably awaits me, ready to tear me to pieces, and I cannot understand how I have fallen into this torment. And Itry licking the honey that once consoled me, but it no longer gives me pleasure. The white mouse and the black mouse – day and night – are gnawing at the branch from which I am hanging. I can see the dragon clearly and the honey no longer tastes sweet. I can see only one thing; the inescapable dragon and the mice, and I cannot tear my eyes away from them. And this is no fable but the truth, the truth that is irrefutable and intelligible to everyone.

“Always the same. Now a spark of hope flashes up, then a sea of despair rages, and always pain; always pain, always despair, and always the same. When alone he had a dreadful and distressing desire to call someone, but he knew beforehand that with others present it would be still worse.”

“Neglecting your health can prevent you from serving people, and too much attention to your body and its health can bring the same results. In order to find the middle way, you should take care of your body only to the extent that doing so helps you to serve others, and does not stop you from serving them. No illness can prevent a person from what he has to do. If you cannot work, then give your love to people. Illnesses of the mind are much more dangerous than illnesses of the body. —MARCUS TULLIUS CICERO”
