nodakāntaritānna dvirna niśāyāṃ na kevalān |

na bhuktvā na dvijaiśchitvā saktūnadyānna vā bahūn ||

lihyānmadhurakāṇāṃ ca cūrṇaṃ madhughṛtānvitam ||

One should not eat roasted flour interspersed with water, nor twice [a day], nor at night, nor by itself alone, / nor after eating [another meal], nor by biting with the front teeth, nor in large quantities. / One should lick the powder of sweet substances mixed with honey and ghee.
