Mbh 13.141.14b

Tranquillity of mind is a high duty that has always been current among them that are righteous. Householders of pure mind are capable of earning very great merit. Indeed, he who cleanses his soul by the performance of the five sacrifices, who is truthful in speech, who is free from malice, who makes gifts, who treats with hospitality and honour all regenerate guests, who lives in well-cleaned abodes, who is free from pride, who is always sincere in his dealings, who uses sweet and assuring words towards others, who takes pleasure in serving guests and others arrived at his abode, and who eats the food that remains after the requirements have been gratified of all the members of his family and dependants, wins great merit. That man who offers water to his guests for washing their feet and hands, who presents the Arghya for honouring the recipient, who duly gives seats, and beds, and lamps for lighting the darkness, and shelter to those that come to his abode, is regarded as highly righteous. That householder who rises at dawn and washes his mouth and face and serves food to his guests, and having honoured them duly dismisses them from his abode and follows them (as a mark of honour) for a little distance, acquires eternal merit. Hospitality towards all, and the pursuit of the aggregate of three, are the duties of the householder. The duties of the Sudra consist in the pursuit of the aggregate of three. The Religion ordained for the householder is said to have Pravritti for its chief indication. Auspicious, and beneficial to all creatures, I shall expound it to thee. The householder should always make gifts according to the measure of his power. He should also perform sacrifices frequently after the same manner. Indeed, he who wishes to achieve his own good should always achieve meritorious acts. The householder, should acquire wealth by righteous means.
