Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Though the embodied soul may be restricted from sense enjoyment, the taste for sense objects remains. But, ceasing such engagements by experiencing a higher taste, he is fixed in consciousness.

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Unless one is transcendentally situated, it is not possible to cease from sense enjoyment. The process of restriction from sense enjoyment by rules and regulations is something like restricting a diseased person from certain types of eatables. The patient, however, neither likes such restrictions nor loses his taste for eatables. Similarly, sense restriction by some spiritual process like astanga-yoga, in the matter of yama, niyama, asana, pranayama, pratyahara, dharana, dhyana, etc., is recommended for less intelligent persons who have no better knowledge. But one who has tasted the beauty of the Supreme Lord Krsna, in the course of his advancement in Krishna consciousness, no longer has a taste for dead, material things. Therefore, restrictions are there for the less intelligent neophytes in the spiritual advancement of life, but such restrictions are only good until one actually has a taste for Krishna consciousness. When one is actually Krishna conscious, he automatically loses his taste for pale things.
