"The bodily conception is created by the desire for material enjoyment. This is called vipada-smṛti, which is the opposite of real life. The living entity is eternally the servant of Kṛṣṇa, but when he desires to enjoy the material world, he cannot progress in spiritual life. One can never be happy by advancing materially. This is also stated in Śrīmad-Bhāgavatam (SB 7.5.30): adānta-gobhir viśatāṁ tamisraṁ punaḥ punaś carvita-carvaṇānām. Through the uncontrolled senses, one may advance one’s hellish condition. He may continue to chew the chewed; that is, repeatedly accept birth and death. The conditioned souls use the duration of life between birth and death only to engage in the same hackneyed activities—eating, sleeping, mating and defending. In the lower animal species, we find the same activities. Since these activities are repeated, engaging in them is like chewing that which has already been chewed. If one can give up his ambition to engage in hackneyed material life and take to Kṛṣṇa consciousness instead, he will be liberated from the stringent laws of material nature. One does not need to make a separate attempt to become liberated. If one simply engages in the service of the Lord, he will be liberated automatically. As Śrīla Bilvamaṅgala Ṭhākura therefore says, muktiḥ svayaṁ mukulitāñjali sevate ’smān: 'Liberation stands before me with folded hands, begging to serve me.'"
