CC Madhya 6.159
cid-aṁśe ‘samvit’, yāre jñāna kari māni
“The three portions of the spiritual potency are called hlādinī [the bliss portion], sandhinī [the eternity portion] and samvit [the knowledge portion]. We accept knowledge of these as full knowledge of the Supreme Personality of Godhead.
To acquire knowledge of the Supreme Personality of Godhead, one must take shelter of the samvit potency of the Supreme Lord.
