But a Brahmana who stays one night only is declared to be a guest (atithi); for because he stays (sthita) not long (anityam), he is called atithi (a guest).
नैकग्रामीणमतिथिं विप्रं साङ्गतिकं तथा । उपस्थितं गृहे विद्याद् भार्या यत्राग्नयोऽपि वा ॥ १०३ ॥
One must not consider as a guest a Brahmana who dwells in the same village, nor one who seeks his livelihood by social intercourse, even though he has come to a house where (there is) a wife, and where sacred fires (are kept).
उपासते ये गृहस्थाः परपाकमबुद्धयः । तेन ते प्रेत्य पशुतां व्रजन्त्यन्नादिदायिनः ॥ १०४ ॥
Those foolish householders who constantly seek (to live on) the food of others, become, in consequence of that (baseness), after death the cattle of those who give them food.
A guest who is sent by the (setting) sun in the evening, must not be driven away by a householder; whether he have come at (supper-) time or at an inopportune moment, he must not stay in the house without entertainment.
