BG Chapters 7 - 12

It is said here that this devotional service is eternally existing. It is not as the Māyāvādī philosophers claim. Although they sometimes take to so-called devotional service, their idea is that as long as they are not liberated they will continue their devotional service, but at the end, when they become liberated, they will "become one with God."

BG 9.2, Purport:

By associating with the sages, Nārada got the taste for hearing and chanting the glories of the Lord, and he developed a great desire for devotional service. Therefore, as described in the Vedānta-sūtra, prakāśaś ca karmaṇy abhyāsāt: if one is engaged simply in the acts of devotional service, everything is revealed to him automatically, and he can understand. This is called pratyakṣa, directly perceived.

The word dharmyam means "the path of religion." Nārada was actually a son of a maidservant. He had no opportunity to go to school. He was simply assisting his mother, and fortunately his mother rendered some service to the devotees. The child Nārada also got the opportunity and simply by association achieved the highest goal of all religion. The highest goal of all religion is devotional service, as stated in Śrīmad-Bhāgavatam (sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje). Religious people generally do not know that the highest perfection of religion is the attainment of devotional service. As we have already discussed in regard to the last verse of Chapter Eight (vedeṣu yajñeṣu tapaḥsu caiva), generally Vedic knowledge is required for self-realization. But here, although Nārada never went to the school of the spiritual master and was not educated in the Vedic principles, he acquired the highest results of Vedic study. This process is so potent that even without performing the religious process regularly, one can be raised to the highest perfection. How is this possible? This is also confirmed in Vedic literature: ācāryavān puruṣo veda. One who is in association with great ācāryas, even if he is not educated or has never studied the Vedas, can become familiar with all the knowledge necessary for realization.

The process of devotional service is a very happy one (su-sukham). Why? Devotional service consists of śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23), so one can simply hear the chanting of the glories of the Lord or can attend philosophical lectures on transcendental knowledge given by authorized ācāryas. Simply by sitting, one can learn; then one can eat the remnants of the food offered to God, nice palatable dishes. In every state devotional service is joyful. One can execute devotional service even in the most poverty-stricken condition. The Lord says, patraṁ puṣpaṁ phalaṁ toyam: He is ready to accept from the devotee any kind of offering, never mind what. Even a leaf, a flower, a bit of fruit, or a little water, which are all available in every part of the world, can be offered by any person, regardless of social position, and will be accepted if offered with love. There are many instances in history. Simply by tasting the tulasī leaves offered to the lotus feet of the Lord, great sages like Sanat-kumāra became great devotees. Therefore the devotional process is very nice, and it can be executed in a happy mood. God accepts only the love with which things are offered to Him.

It is said here that this devotional service is eternally existing. It is not as the Māyāvādī philosophers claim. Although they sometimes take to so-called devotional service, their idea is that as long as they are not liberated they will continue their devotional service, but at the end, when they become liberated, they will "become one with God." Such temporary time-serving devotional service is not accepted as pure devotional service. Actual devotional service continues even after liberation. When the devotee goes to the spiritual planet in the kingdom of God, he is also engaged there in serving the Supreme Lord. He does not try to become one with the Supreme Lord.

As will be seen in Bhagavad-gītā, actual devotional service begins after liberation. After one is liberated, when one is situated in the Brahman position (brahma-bhūta (SB 4.30.20)), one's devotional service begins (samaḥ sarveṣu bhūteṣu mad-bhaktiṁ labhate parām). No one can understand the Supreme Personality of Godhead by executing karma-yoga, jñāna-yoga, aṣṭāṅga-yoga or any other yoga independently. By these yogic methods one may make a little progress toward bhakti-yoga, but without coming to the stage of devotional service one cannot understand what is the Personality of Godhead. In the Śrīmad-Bhāgavatam it is also confirmed that when one becomes purified by executing the process of devotional service, especially by hearing Śrīmad-Bhāgavatam or Bhagavad-gītā from realized souls, then he can understand the science of Kṛṣṇa, or the science of God. Evaṁ prasanna-manaso bhagavad-bhakti yogataḥ. When one's heart is cleared of all nonsense, then one can understand what God is. Thus the process of devotional service, of Kṛṣṇa consciousness, is the king of all education and the king of all confidential knowledge. It is the purest form of religion, and it can be executed joyfully without difficulty. Therefore one should adopt it.
