(Bhakti Sandarbha: 7)
“If, through hearing deliberation upon the meaning of all the śāstras beginning with Vedānta from a sad-guru, that [i.e., bhakti] is understood to be the supreme necessary duty, and furthermore … if they [i.e., listeners] develop capability for contemplation, and absorption in contemplation, which dispel contradictory notions, then that, bhakti, is attainable through upāsana by those endowed with śraddhā.”
