BHAKTI AND GNANA
Narada the foremost among devotees is always engaged in singing Hari Kirtan (glories of Hari) and narrating His stories. From this we can conclude that devotion or bhakti manifests only through these two, that is kirtan and Harikatha.
Dakshinamoorthy the foremost among the gnanis (enlightened ones) is always observing silence. From this it can be seen that gnana (wisdom) in a person is manifest only through silence.
