About
"[The Supreme Personality of Godhead, Krishna, said:] ‘My dear Uddhava, neither through ashtanga-yoga [the mystic yoga system to control the senses], nor through impersonal monism or an analytical study of the Absolute Truth, nor through study of the Vedas, nor through austerities, charity or acceptance of sannyasa can one satisfy Me as much as by developing unalloyed devotional service unto Me.’" (Shrimad Bhagavatam, 11.14.20)
