Celibacy, and non-violence are called austerity of the body.

The worship of Devas, Braahmana, guru, and the wise; purity, honesty, celibacy, and nonviolence; these are said to be the austerity of deed.
The austerity of the body consists in this: worship of the Supreme Lord, the brahmanas, the spiritual master, and superiors like the father and mother. Cleanliness, simplicity, celibacy and nonviolence are also austerities of the body.
