Shloka 12
महाभूत–इन्द्रिय–मनस्–बुद्धि–अन्तरात्मा विवेकः | Discrimination of Elements, Senses, Mind, Intellect, and Inner Self
दन्तोलूखलिका: केचिदश्मकुट्टास्तथा परे | शुक्लपक्षे पिबन्त्येके यवागूं क्वथितां सकृत्
dantolūkhalikāḥ kecid aśmakuṭṭās tathā pare | śuklapakṣe pibanty eke yavāgūṃ kvathitāṃ sakṛt ||
毗耶娑说：有的人以齿为臼而嚼碎食物，有的人则以石捣之。在白半月（śukla-pakṣa）之时，有的人每日仅一次饮用一份煮熟的稀粥（yavāgū）。此皆显示求道者以种种严苦之行，抑制口腹之欲，培育自制之力。
