Flour Instead of Bread
In Europe, on one occasion, remembering the desperate days in Ṭihrán when Bahá’u’lláh was incarcerated, their home sacked and their properties confiscated, ‘Abdu’l-Bahá could yet say, “Detachment does not imply lack of means; it is marked by the freedom of the heart. In Ṭihrán, we possessed everything at a nightfall, and on the morrow we were shorn of it all, to the extent that we had no food to eat. I was hungry, but there was no bread to be had. My mother poured some flour into the palm of my hand, and I ate that instead of bread. Yet, we were contented.”
