devotional service to the Personality

"It is true that by practicing restraint of the senses by the yoga
system one can get relief from the disturbances of desire and lust,
but this is not sufficient to give satisfaction for the soul, for this
[satisfaction] is derived from devotional service to the Personality
of Godhead."

(Sri Narada Muni - Srimad-Bhagavatam 1.6.35)
