From
"How to become Holy"written in 1453 by Abu Abdallah Muhammad Al-Jazuli Al-Simlali.
In order to eliminate feelings of self-importance, he who would become holy would do well to acquire the Ten Praiseworthy Attributes of the Dog:
1. He sleeps only a little at night; this is a sign of the God-lover.
2. He complains of neither heat nor cold; this is a sign of patient endurance.
3. When he dies, he leaves nothing behind to be disposed of; this is a sign of asceticism.
4. He is neither angry nor hateful; this is a quality of the faithful.
5. He is not sorrowful at the loss of a close relative, nor does he accept assistance; this is an attribute of the unshakeable.
6. If he is given something, he consumes it and is happy; this is a sign of the never-demanding.
7. He has no known place of refuge; this is the quality of holy wandering.
8. He sleeps in any place that he finds; this is a quality of the never-complaining.
9. He is incapable of hate, even if his owner beats or starves him; this is a quality of the knowers of wisdom.
(Compare the injunction in the Hindu Upanishads: "Be like the sandalwood that perfumes the axe that hacks it.")10. He is always hungry, which is a sign of the virtuous.
These attributes were amongst those of the black (therefore despised) Moroccan saint,
Abu Yi'zza.
