大慧普覺禪師宗門武庫 1.76

1.76

無盡居私第日，適年荒，有道士輩，詣門教化食米，無盡遂勸各人誦《金剛經》，若誦得一分，施米一斗，如誦畢施米三石二斗，化渠結般若緣，故云：「財法二施。」每遇僧又勸念《老子》，使其互相知有。觀其護教之心，直如是爾。

When Wujin was living in his private residence, it happened to be a year of famine. Some Daoists came to his gate to beg for rice. Wujin thereupon encouraged each of them to chant the Diamond Sūtra: if they could chant one section, he would donate one peck of rice; if they chanted the whole text, he would donate three stones and two pecks of rice, leading them to form an affinity with prajñā. Hence it is said: "The two kinds of giving: material and Dharma." Whenever he encountered monks, he would in turn encourage them to recite the Laozi, causing them to recognize one another. Observing his mind to protect the teaching, it was simply like this.
