nāsnāto naiva saṃviṣṭo na caivānyamanā naraḥ //

“Hot when unbathed, nor when reposing, nor while thinking of other things, nor when sitting on his bed or on the earth, nor when making a sound,[10] nor when clad in a single garment, nor when speaking, nor without giving to spectators, but when bathed a man should eat evening and morning according to rule.
