“Indeed, the truth that many people never understand, until it is too late, is that the more you try to avoid suffering, the more you suffer, because smaller and more insignificant things begin to torture you, in proportion to your fear of being hurt. The one who does most to avoid suffering is, in the end, the one who suffers the most: and his suffering comes to him from things so little and so trivial that one can say that it is no longer objective at all. It is his own existence, his own being, that is at once the subject and the source of his pain, and his very existence and consciousness is his greatest torture.”

Context: What does the Scripture mean when it tells us of the body of one man so extended in space that all can kill him? We must understand these words of ourselves, of our Church, or the body of Christ. For Jesus Christ is one man, having a Head and a body. The Saviour of the body and the members of the body are two in one flesh, and in one voice, and in one passion, and, when iniquity shall have passed away, in one repose.
And so the passion of Christ is not in Christ alone; and yet the passion of Christ is in Christ alone. For if in Christ you consider both the Head and the body, the Christ’s passion is in Christ alone; but if by Christ you mean only the Head, then Christ’s passion is not in Christ alone. Hence if you are in the members of Christ, all you who hear me, and even you who hear me not (though you do hear, if you are united with the members of Christ), whatever you suffer at the hands of those who are no among the members of Christ, was lacking to the sufferings of Christ. It is added precisely because it was lacking. You fill up the measure; you do not cause it to overflow. You will suffer just so much as must be added of your sufferings to the complete passion of Christ, who suffered as our Head and who continues to suffer in His members, that is, in us. Into this common treasury each pays what he owes, and according to each one’s ability we all contribute our share of suffering. The full measure of the Passion will not be attained until the end of the world.

Du kannst Dich zurückhalten von den Leiden der Welt, das ist Dir freigestellt und entspricht Deiner Natur, aber vielleicht ist gerade dieses Zurückhalten das einzige Leid, das Du vermeiden könntest.

Love is not a feeling ~ The Article (1995)
Context: In other words, to be enlightened of the acquired burden every spiritual belief and notion has to be abandoned, every reference to what any spiritual teacher or master has ever said must be set aside. What does that leave? Your own experience. Not your historical or memorable experience, for that's the problem. Your own experience is your self-knowledge of life. Let's establish once and for all what this means now. Forget everything I've said in this article except this question: Do I want to suffer or not suffer NOW? That's the only truth for you. There's no tradition, no past, no discussion in it. It's all you need. Keep it with you and at the next temptation to suffer it will prevent you suffering. But only if you've learned in your own experience what causes you to suffer. If you haven't learned that, you're still attached to suffering and will unwittingly embrace it. In that case you have to read on, take more time and ask yourself more questions.
