SB 10.7.32

Nanda Mahārāja confirmed that by pious activities one can become a sādhu so that one will be happy at home and one’s children will be protected. In śāstra there are many injunctions for karmīs and jñānīs, especially for karmīs, by which they can become pious and happy even in material life. According to Vedic civilization, one should perform activities for the benefit of the public, such as constructing public roads, planting trees on both sides of the road so that people can walk in the shade, and constructing public wells so that everyone can take water without difficulty. One should perform austerity to control one’s desires, and one must simultaneously worship the Supreme Personality of Godhead. Thus one becomes pious, and as a result one is happy even in material conditions of life.
