It was precisely prayer that helped me overcome every crisis.

I believe that the sufferings of hunger that we endured during the war in prison were somewhat easier for me to bear, thanks in part to the fasting, self-denial, and acts of penance I once imposed on myself. The experience of hunger was at least not new to me; the only difference was in its intensity. And soon I realized that while prayer does not alleviate physical suffering or mental distress, it allows one to endure them more patiently. And surely it was through prayer that I was able to overcome every crisis.
