It is not difficult to have occult or psychic powers; to be virtuous is not difficult, nor to keep our life pure. But to be merciful, to be compassionate, to be human, is difficult.

One should go into one's room at night and repent of what one has done, of all the thousand bad thoughts one has had of friends and enemies. A Persian poet says, 'The whole secret of the two worlds is in these two words: with thy friends be loving, with thy enemies courteous.'
