Fruitive activities (seeking sense gratification) are cause for material bondage. As long as one is engaged in activities aimed at improving the standard of bodily comfort, one is sure to transmigrate to different types of bodies, thereby continuing material bondage perpetually. Çrémad-Bhägavatam confirms this as follows:

Therefore, jïäna (or knowledge that one is not this material body but spirit soul) is not sufficient for liberation. One has to act in the status of spirit soul, otherwise there is no escape from material bondage. Action in Kåñëa consciousness is not, however, action on the fruitive platform. Activities performed in full knowledge strengthen one's advancement in real knowledge. Without Kåñëa consciousness, mere renunciation of fruitive activities does not actually purify the heart of a conditioned soul. As long as the heart is not purified, one has to work on the fruitive platform. But action in Kåñëa consciousness automatically helps one escape the result of fruitive action so that one need not descend to the material platform. Therefore, action in Kåñëa consciousness is always superior to renunciation, which always entails a risk of falling. Renunciation without Kåñëa consciousness is incomplete, as is confirmed by Çréla Rüpa Gosvämé in his Bhakti-rasämåta-sindhu.
