2.111

僧祇云比丘籴貯穀米。應作是念。我當依是。得誦經坐禪行道。到穀貴時。若食長（音伩）若作功德。餘者粜之。

The Mahāsāṃghika-vinaya says: 'When a monk purchases and stores grain and rice, he should entertain this thought: "Relying on this, I shall be able to recite sūtras, sit in meditation, and practice the Way." When the time comes that grain is dear, if he eats it, it is a surplus; if he makes merit, the remainder may be sold.'
