vittaisanam yajña-danair
grhair dara-sutaisanam
atma-lokaisanam deva
kalena visrjed budhah
grame tyaktaisanah sarve
yayur dhiras tapo-vanam
Translation:
An intelligent person should learn to renounce his desire for wealth by performing sacrifices and acts of charity. He should learn to renounce his desire for wife and children by experiencing family life. And he should learn to renounce his desire for promotion to a higher planet in his next life, O saintly Vasudeva, by studying the effects of time. Self-controlled sages who have thus renounced their attachment to household life go to the forest to perform austerities.
