Ariya-vamsa: The four Noble Usage’s, are:
1: Contentedness of the Bhikkhu with any robe,
2: C ontentedness with any Alms-food,
3: Contentedness with any dwelling,
4L Delight in meditation and detachment.
In the Ariya-vamsa Sutta, A. IV, 28 and similarly in D. 33, it is said:

Now the Bhikkhu is contented with any robe, with any alms-food, with any dwelling, finds pleasure and enjoyment in mental training and detachment. But neither is he haughty on that account, nor does he look down upon others. Now, of a Bhikkhu who herein is fit and indefatigable, who remains aware and clearly comprehending, of such a Bhikkhu it is said that he is firmly established in the ancient lineage of Noble Usage known as the most lofty one.
