samplavaḥ sarvabhūtānāṃ vikramaḥ pratisaṅkramaḥ /
iṣṭāpūrtasya kāmyānāṃ trivargasya ca yo vidhiḥ //

21. What is the nature of the intermediate deluges, (the creation, the preservation and the destruction of all the created beings)? What is the unobjectionable method of doing charitable works such as sacrificial worship and constructing lakes and tanks and of performing Agnihotra and other duties towards temporary ends, and in short what is the method of working for Dharma, Artha and Kama?
