4.15.23

tasmāt parokṣe 'smad-upaśrutāny alaṃ kariṣyatha stotram apīcya-vācaḥ /
saty uttamaśloka-guṇānuvāde jugupsitaṃ na stavayanti sabhyāḥ //

23. So, do you out of our hearing and in after times take up the celebration of our renown, O bards of sweet words; when there is necessity for repeatedly singing the excellent qualities of Hari of the purest renown, worthy men do not give their praise to low objects.
