‘Venerable Nāgasena, those three qualities of food you say he ought to take, which are they?’

‘Just, O king, as food is the support of all beings, just so, O king, should the strenuous Bhikshu, earnest in effort, be a handle, as it were, by which all beings may open the door of the noble eightfold path. This, O king, is the first of the qualities of food he ought to have.

‘And again, O king, just as food increases people’s strength; just so, O king, should the strenuous Bhikshu, earnest in effort, grow in increase of virtue. This, O king, is the second of the qualities of food he ought to have.

‘And again, O king, just as food is a thing desired of all beings; just so, O king, should the strenuous Bhikshu, earnest in effort, be desired of all the world. This, O king, is the third of the qualities of food he ought to have. For it was said, O king, by Mahā Moggallāna, the Elder:

“By self-restraint, training, and righteousness,
By duty done, and by attainments reached,
The strenuous recluse should make himself
To all men in the world a thing desired “’
