分別功德論 4.30

4.30

所以言金毘羅比丘者，常行七家乞食，不得過七。所以然者，立誓限七故也。乞食時欲福度眾生，專心念道無有貪想，若得好惡不以增減，隨次乞食不擇貧富。若一家二家得食時，更有布施者，足則止、不足便受。若至七家不得食者，便還所止思惟行道，不念明日當至某家、不至某家，都無分別之想，故名七家沙門也。還則靜坐斂心在道，故稱金毘羅於七家乞食為第一也。

The reason why the bhikṣu Kimbila is mentioned is that he constantly engaged in begging at seven houses, never exceeding seven. The reason for this is that he made a vow limiting it to seven. When begging for food, desiring to bring merit and deliverance to sentient beings, he single-mindedly contemplated the Way without greedy thoughts; whether he received good or bad [food], he did not increase or decrease [his contentment], begging in consecutive order without selecting between poor and rich. When receiving food from one or two houses, if there were further donors, if it was sufficient he stopped, and if insufficient he accepted. If he reached seven houses without obtaining food, he returned to his dwelling to contemplate and practice the Way, never thinking, 'Tomorrow I will go to such-and-such a house and not to that house,' being entirely free of discriminatory thoughts; hence he is called the 'seven-house śramaṇa'. Upon returning, he sat quietly and collected his mind in the Way. Therefore, Kimbila is called foremost in begging for food at seven houses.
