The residue of food and drink, as also the flowers with which one has adored the celestials, should never be used. Inviting a guest at night, one should never, with excessive courtesy, compel him to eat to his fill. Nor should one cat to his fill, at night.
शेषाणि चैव पानानि पानीयं चापि भोजने। सौहित्यं न च कर्तव्यं रात्रौ न च समाचरेत्॥
