It has been explained by Srila Prabhupada many times earlier also that one cannot artificially renounce everything by the process of astanga yoga or hath yoga or any yoga. Even if one tries so, he will fall down again into the material pool. Like mayavadis, they renounce everything saying, neti neti neti, but then agitated by such artificial renunciation they again comes back to the material world. This is why there is a chance of fall down even after liberation. But a devotee in Kṛṣṇa Consciousness is directly under the guidance of the Supreme Lord Kṛṣṇa. He will only do what Kṛṣṇa will ask him to do. He may be on the sensual platform, but because he is Kṛṣṇa Conscious, he has no attachment to such sensual things. A Kṛṣṇa Conscious person is only after the satisfaction of Kṛṣṇa and nothing else. If Kṛṣṇa wants, he may do something which is ordinarily undesirable and if Kṛṣṇa doesn't wants, he won't do which he can do ordinarily for his sense gratification. So to do or not do is under his control because he only acts as per the direction of Krishna. Such consciousness is the complete mercy of the Lord a devotee gets despite of he being on the sensual platform.
