Verse 302

किं वास इति यदिदं किंचाश्वभ्य आ कृ-मिभ्य आ कीटपतङ्गेभ्यस्तत्तेऽन्नमापो वा-स इति न ह वा अस्यानन्नं जग्धं भवतिनानन्नं प्रतिगृहीतं य एवमेतदनस्यान्नंवेद तद्विद्वाँसः श्रोत्रिया अशिष्यन्तआचामन्त्यशित्वाचामन्त्येतमेव तदनम-नग्नं कुर्वन्तो मन्यन्ते ॥ १४ ॥

In plain words

'And what do I wear?' he asked. 'Everything there is,' they answered, 'from horses down to worms, down to insects and moths — that is your food, and water is your covering.' Once you know that this is the Eater's food, nothing you eat is ever really not-food, nothing you take in is ever wrongly taken. That is why the learned, the scholars steeped in the Veda, always rinsed their mouths with water — once before eating and once after — believing that this simple act clothes the food, covers what would otherwise stand bare.

Close to the Sanskrit

'Or what is [my] clothing?' — [he asked]. 'Whatever there is here, from horses down to worms, down to insects and moths, that is your food; water is [your] clothing' — thus [they said]. Indeed, verily, for him nothing that is not food is ever eaten, nothing that is not food is accepted, for one who thus knows this food of the Eater. Accordingly, the learned, the Vedic scholars, used to observe [this teaching]: they sip water, having eaten they sip water again, believing that they thereby make that very food not naked. [14]
