When love of God deteriorates into lust, it is very difficult to return to the normal condition. Nonetheless, Kṛṣṇa consciousness is so powerful that even a late beginner can become a lover of God by following the regulative principles of devotional service. So, from any stage of life, or from the time of understanding its urgency, one can begin regulating the senses in Kṛṣṇa consciousness, devotional service of the Lord, and turn the lust into love of Godhead—the highest perfectional stage of human life.
