四分律行事鈔資持記 2.1186

2.1186

六中。言非心者，由不對境，直爾自取，故無受心。如上，即《僧祇》、《多論》取石上故食。儉開即本宗八事。

In the sixth: "without mind" means that because one does not face an object counterpart and simply takes it oneself directly, there is no mind of reception. "As above" refers to the Mahāsāṃghika-vinaya and Sarvāstivāda Vinaya Vibhāṣā regarding taking leftover food on rocks. The famine exceptions are the eight matters of our own school.
