Krishna consciousness does not deny the devotee the right to gratify his senses; it orders that we do it only in an authorized way. If we don’t accept such spiritual discipline, how can we expect to advance in Krishna consciousness to the point where we attain Krishna? The material world is a dangerous place. If we don’t come to Krishna consciousness and accept austerities on Krishna’s behalf, then we will not be able to negotiate this world safely. Actually, austerities performed on the Lord’s behalf deliver nectar. Narada Muni states that one who has actually experienced the taste of devotional service will not forget the ecstasy ever again. He may foolishly go out and try to again enjoy separately from Krishna, collecting the seeds of karma in this world, but he will always be haunted by the taste of surrender to Krishna.
