PURPORT

"One should render transcendental loving service to the Supreme Lord Krsna favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." One simply has to concentrate upon the lotus feet of Vasudeva, Krsna (sa vai manah krsna-padaravindayoh). Then the mind and senses will be controlled, and one can engage himself fully in the devotional service of the Lord. The devotee does not need to practice the hatha-yoga system to control the mind and senses; his mind and senses are automatically controlled because of unalloyed devotional service to the Lord.
