rasa-varjam raso 'py asya
param drishtva nivartate
The embodied soul may be restricted from sense enjoyment, though the taste for sense objects remains. But, ceasing such engagements by experiencing a higher taste, he is fixed in consciousness.
Krishna continues on the subject of the nature of the sense control. Here, He compares the two forms of sense control. One is to restrict the senses from their objects, which the yogis tend to do. They give up eating, sleeping or any kind of activity that gives the senses an opportunity to enjoy. They renounce their family and friends, become reclusive and live very hard and austere lives. Despite the external denial of the senses, the taste or hankering for enjoyment will remain, which will cause the eventual downfall of the yogis.
The second option Krishna proposes is called the "higher taste." Here the senses are fully engaged, not for the purpose of personal gratification, but for the pleasure of the Lord. Example the ears like pleasing music, but instead of hearing mundane music one listens to devotional songs. Similarly the tongue likes to vibrate (talk) and taste. This could be done as devotional service by engaging the tongue in Krishna-katha and eating prasadam. Since the senses are fully engaged there is now no chance of their fall down. Srila Prabhupada explains, "But one who has tasted the beauty of the Supreme Lord Krishna, in the course of his advancement in Krishna consciousness, no longer has a taste for dead, material things."
In text 60-63 Krishna builds on this specifically in context to Arjuna's plan to renounce work and go to the forest to "gain knowledge" and avoid sinful reactions.
