महाभारत - उद्योग - मुनिः

उत्पाद्य पुत्राननृणांश्च कृत्वा
    वृत्तिं च तेभ्योऽनुविधाय कांचित् ।
स्थाने कुमारीः प्रतिपाद्य सर्वाः
    अरण्यसंस्थोऽथ मुनिर्बुभूषेत् ॥

One must beget children. He must make his son free from any debt. Teach him something using which he can earn some money. He must get all his daughters married and settled in good. After all that he must go to a forest and desire to become a saint.
