Elif Shafak. Architect's apprentice (№ 418095)

In paradise grows a tree that is not like all the others. Its branches are transparent as glass, the roots absorb milk, not water, the trunk emits a glow, as if covered with ice frost. But he who approaches this tree does not experience cold, for it is never cold. Every leaf on this tree bears the name of a person. Once a year, in the month of Shaaban, on the night of the fourteenth to the fifteenth, angels fly to this tree, surround it and at the same time flap their wings. The wind rises, which shakes the transparent branches of the tree. Some leaves break off and fall to the ground. Sometimes the leaf has to hang on the tree for a long, very long time. Sometimes he falls, barely having time to bloom. The moment the leaf touches the ground, the person whose name it bears emits its last breath. Therefore, people endowed with wisdom and knowledge never step on dry leaves. They know that they used to be someone's souls.
