In the bhakti-mārga, the path of devotional service, one must strictly follow the regulative principles by first controlling the tongue (sevonmukhe hi jihvādau svayam eva sphuraty adaḥ). The tongue (jihvā) can be controlled if one chants the Hare Kṛṣṇa mahā-mantra, does not speak of any subjects other than those concerning Kṛṣṇa and does not taste anything not offered to Kṛṣṇa. If one can control the tongue in this way, brahmacarya and other purifying processes will automatically follow. It will be explained in the next verse that the path of devotional service is completely perfect and is therefore superior to the path of fruitive activities and the path of knowledge.

Because of ignorance, one speculatively thinks himself liberated from material contamination although actually he is not. Therefore even if one rises to brahma jñāna, understanding of Brahman, one nevertheless falls down because of not taking shelter of the lotus feet of Kṛṣṇa. Nonetheless, jñānīs at least know what is sinful and what is pious, and they very cautiously act according to the injunctions of the śāstras.

As stated in Bhagavad-gītā (7.19), one attains real knowledge when he understands Kṛṣṇa and surrenders unto Him (bahūnāṁ janmanām ante jñānavān māṁ prapadyate). To become learned and free from material contamination, therefore, one should try to understand Kṛṣṇa, for thus one is immediately liberated from all pious and impious activities and their reactions.

Before one’s next death comes, as long as one’s body is strong enough, one should quickly adopt the process of atonement according to śāstra; otherwise one’s time will be lost, and the reactions of his sins will increase. As an expert physician diagnoses and treats a disease according to its gravity, one should undergo atonement according to the severity of one’s sins.

Lord Kṛṣṇa urges that one give up all other duties and surrender to Him, and He promises, ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi: “I shall free you from all sinful reactions and give you liberation.” Therefore in response to the inquiries of Parīkṣit Mahārāja, Śukadeva Gosvāmī, his guru, could have immediately explained the principle of bhakti, but to test Parīkṣit Mahārāja’s intelligence, he first prescribed atonement according to karma-kāṇḍa, the path of fruitive activities.

Because a Vaiṣṇava fully takes shelter of the Supreme Personality of Godhead, he personally has no problems, but because he is compassionate toward the fallen, conditioned souls, he is always thinking of plans to save them from their hellish life in this body and the next. Parīkṣit Mahārāja, therefore, anxiously wanted to know from Śukadeva Gosvāmī how humanity can be saved from gliding down to hell.

Atheists try to conceal the hand of God, which is present in every creation, but they cannot explain how all these creations could come into existence without a competent intelligence and almighty power behind them. Simply to imagine or speculate is a waste of time.

Learned men, therefore, must be cautious of this age, and if they at all want to cross over the dangerous ocean of Kali, they must follow the footsteps of the sages of Naimiṣāraṇya and accept Śrī Sūta Gosvāmī or his bona fide representative as the captain of the ship. The ship is the message of Lord Śrī Kṛṣṇa in the shape of Bhagavad-gītā or the Śrīmad-Bhāgavatam.

All living entities are rotating throughout the universe, going sometimes up to the higher planetary systems and sometimes down to the lower planets. This is the material disease, which is known as pravṛtti-mārga. When one becomes intelligent he takes to nivṛtti-mārga, the path of liberation, and thus instead of rotating within this material world, he returns home, back to Godhead. This is necessary.

Bhakti-yoga, however, is so powerful that it does not depend on karma-yoga or jñāna-yoga. Bhakti-yoga itself is so powerful that even an impious man with no assets in karma-yoga or an illiterate with no assets in jñāna-yoga can undoubtedly be elevated to the spiritual world if he simply adheres to bhakti-yoga.
