SB 12.12.54
yasah-sriyam eva parisramah paro
varnasramacara-tapah-srutadisu
avismrtih sridhara-pada-padmayor
gunanuvada-sravanadaradibhih
Translation:
The great endeavor one undergoes in executing the ordinary social and religious duties of the varnasrama system, in performing austerities, and in hearing from the Vedas culminates only in the achievement of mundane fame and opulence. But by respecting and attentively hearing the recitation of the transcendental qualities of the Supreme Lord, the husband of the goddess of fortune, one can remember His lotus feet.
