The intelligent man situated in Krsna consciousness does not try to forcibly stop his senses from acting. Rather, he engages his senses in the service of Krsna. No one can stop a child from playing by leaving him inactive; rather, one can stop the child from engaging in nonsense by engaging him in superior activities. Similarly, the forceful restraint of sense activities by the eight principles of yoga is recommended for inferior men; superior men, being engaged in the superior activities of Krsna consciousness, naturally retire from the inferior activities of material existence.
