सुखं न कृषितोऽन्यत्र यदि धर्मेण वर्तते |
अवस्त्रत्वं निरन्नत्वं कृषितो नैव जायते ||
-बृहत् पराशर स्मृति
A farmer will always be happy as long as he leads his life following Dharma (moral code of life). He should respect the land and not try to exploit. If he lives like that, he will never go hungry or without clothes.
- Bruhat Parashara Smriti
