Narada Bhakti Sutra, Aphorism 76

Devotional Scriptures are to be pondered over, and works that increase devotion should be performed.
Discussion is either destructive or constructive. The former is “vain.” Leave others their theories and systems: be satisfied with building and expressing your own. Work upon those books which develop your own idiosyncrasies—in this case bhakti, Love.
