The wise have said that the excavation of a tank brings on Virtue, Profit and Pleasure. A tank is said to be properly excavated, if it is made on a piece of land that is inhabited by respectable persons. A tank is said to be necessary for all the four purposes of living creatures. Thanks, again, are considered as forming the excellent beauty of a country.
धर्मस्यार्थस्य कामस्य फलमाहुर्मनीषिणः। तडागसुकृतं देशे क्षेत्रमेकं महाश्रयम्॥ चतुर्विधानां भूतानां तडागमुपलक्षयेत्। तडागानि च सर्वाणि दिशन्ति श्रियमुत्तमाम्॥
