Jayapataka Swami: Srimad Bhagavatam 1.2.6 Translation:  The supreme occupation [dharma] for all humanity is that by which men can attain to loving devotional service unto the transcendental Lord. Such devotional service must be unmotivated and uninterrupted to completely satisfy the self.
The question was, what sinful life has to do with this? Obviously, the sinful activities are interruptions to our bhakti. And therefore, the pure bhakti is satisfying to the self, but if they are interrupted by sin, they will not be satisfying to the self. Therefore, the four pillars of irreligiosity are forbidden.
