Mahabharata — Anushasana Parva, Shloka 13
Sāma (Sāntva) and Dāna: The Brāhmaṇa’s Conciliatory Release from a Rākṣasa
प्रभुर्वान्निमदन् विद्वान् पुनर्जनयतीश्वर: । स चाजन्नाज्जायते तस्मात् सूक्ष्म एष व्यतिक्रम:
prabhur vānnimadan vidvān punar janayatīśvaraḥ | sa cājann āj jāyate tasmāt sūkṣma eṣa vyatikramaḥ ||
弥勒耶说道：有能力而明辨、具足威力之人，虽食于粮，却又能使粮食再度生起；然而他自身亦由食而生。故此种“倒转”幽微难知——诚然，食由雨生，众生由食生；但说食又由众生（如博学的婆罗门）而生，其理并不易明。

Educational Q&A
The verse highlights a subtle interdependence in the moral-cosmic economy: beings depend on food, yet through their agency (work, sacrifice, governance, learning, and right conduct) they also become causes for the renewed production and distribution of food. This apparent reversal of cause and effect is presented as difficult to grasp.
Maitreya is explaining a nuanced point about origins and sustenance: although rain produces food and food produces living beings, it is also said that living beings—exemplified by a learned brāhmaṇa—bring about food again. He notes that this reciprocal causality is subtle and not straightforward.
