(Lord Krishna delivers His devotee from the ocean of birth and death)
"A child is completely cared for by his parents, and thus his position is secure. Similarly, a devotee does not need to endeavor to transfer himself by yoga practice to other planets. Rather, the Supreme Lord, by His great mercy, comes at once, riding on His bird carrier Garuḍa, and at once delivers the devotee from material existence. Although a man who has fallen in the ocean may struggle very hard and may be very expert in swimming, he cannot save himself. But if someone comes and picks him up from the water, then he is easily rescued. Similarly, the Lord picks up the devotee from this material existence. One simply has to practice the easy process of Kṛṣṇa consciousness and fully engage himself in devotional service. Any intelligent man should always prefer the process of devotional service to all other paths. In the Nārāyaṇīya this is confirmed as follows:
yā vai sādhana-sampattiḥ puruṣārtha-catuṣṭaye
tayā vinā tad āpnoti naro nārāyaṇāśrayaḥ
The purport of this verse is that one should not engage in the different processes of fruitive activity or cultivate knowledge by the mental speculative process. One who is devoted to the Supreme Personality can attain all the benefits derived from other yogic processes, speculation, rituals, sacrifices, charities, etc. That is the specific benediction of devotional service.
Simply by chanting the holy name of Kṛṣṇa—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—a devotee of the Lord can approach the supreme destination easily and happily, but this destination cannot be approached by any other process of religion.
The conclusion of Bhagavad-gītā is stated in the Eighteenth Chapter:
sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja
ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi mā śucaḥ
One should give up all other processes of self-realization and simply execute devotional service in Kṛṣṇa consciousness. That will enable one to reach the highest perfection of life. There is no need for one to consider the sinful actions of his past life, because the Supreme Lord fully takes charge of him. Therefore one should not futilely try to deliver himself in spiritual realization. Let everyone take shelter of the supreme omnipotent Godhead, Kṛṣṇa. That is the highest perfection of life."
