1.5.22

idaṃ hi puṃsastapasaḥ śrutasya vā sviṣṭasya sūktasya ca buddhidattayoḥ /
avicyuto 'rthaḥ kavibhirnirūpito yaduttamaślokaguṇānuvarṇanam //

22. The real and eternal, intrinsic and necessary purpose of man to be attained by means of *Tapas*, studies, sacrifices, the construction of tanks and wells etc. and by means of what is learnt and what is given away in charity, is indeed, the wise say, to sing with devotion the excellent powers of that glorious Lord.
