The scriptures have declared that among birds, the crow is the meanest; among animals, the donkey is the meanest and among men, the one who indulges in slander is most despicable. The crow is mean because it does not relish good food and prefers only rotten things. The donkey carries only dirty clothes and is always dirty. The slanderer has a foul tongue and is the meanest among human beings. (Vol 20, p.55)
One animal which is viewed with contempt is the donkey. But there are quite a few virtues man can learn from the donkey. The quality of patience to be found in a donkey is not found even in man. Whatever burdens may be heaped on its back, it bears them all with forbearance. It puts up with any amount of beatings. Even when it is starved of food and water, it presents a calm face. Man has thus to learn the quality of forbearance from the donkey. (SSS Vol.30, p. 15)
