Mbh 12.243.1a

"'"Vyasa said, 'Observant of meritorious vows, the householder, for the second period of life, should dwell in his house, having taken spouses according to the ways indicated in the ordinance and having established a fire (of his own). As regards the domestic mode of life, four kinds of conduct have been laid down by the learned. The first consists of keeping a store of grain sufficient to last for three years. The second consists of keeping a store to last for one year. The third consists of providing for the day without thinking of the morrow. The fourth consists of collecting grain after the manner of the pigeon.[998] Of these, each succeeding one is superior in point of merit to that which precedes it, according to what has been laid down in the scriptures.[999] A householder observing the first kind of conduct may practise all the six well-known duties (viz., sacrifice on his own account, sacrifice on that of others, teaching, learning, making gifts, and accepting gifts). He who observes the second kind of conduct should practise three only, of these duties (viz., learning, giving, and taking). He who observes the third kind of conduct should practise only two of the duties of domesticity (viz., learning and giving). The householder practising the fourth kind of domesticity should observe only one duty (viz., learning the scriptures). The duties of the householder are all said to be exceedingly meritorious. The householder should never cook any food for only his own use; nor should he slaughter animals (for food) except in sacrifices.[1000] If it be an animal which the householder desires to kill (for food), or if it be a tree which he wishes to cut down (for fuel), he should do either act according to the ritual laid down in the Yajuses for that much is due to both animate and inanimate existences. The house-holder should never sleep during the day, or during the first part of the night, or during the last part thereof.
