Since Mahārāja Parīkṣit was a great devotee. the answers of his guru, Śukadeva Gosvāmī, concerning karma-kāṇḍa and jñāna-kāṇḍa could not satisfy him. Therefore Śukadeva Gosvāmī, knowing very well the heart of his disciple, explained the transcendental bliss of devotional service.

SB Canto 6

SB 6.1.15, Purport: Speculators who undergo great labor to gain a meticulous understanding of the material world by distinguishing between sinful and pious activities, but who are not situated in devotional service, are prone to material activities. They may fall down and become implicated in fruitive activities. If one becomes attached to devotional service, however, his desires for material enjoyment are automatically vanquished without separate endeavor. Bhaktiḥ pareśānubhavo viraktir anyatra ca: [SB 11.2.42] if one is advanced in Kṛṣṇa consciousness, material activities, both sinful and pious, automatically become distasteful to him. That is the test of Kṛṣṇa consciousness. Both pious and impious activities are actually due to ignorance because a living entity, as an eternal servant of Kṛṣṇa, has no need to act for his personal sense gratification. Therefore as soon as one is reclaimed to the platform of devotional service, he relinquishes his attachment for pious and impious activities and is interested only in what will satisfy Kṛṣṇa. This process of bhakti, devotional service to Kṛṣṇa (vāsudeva-parāyaṇa), relieves one from the reactions of all activities.

Since Mahārāja Parīkṣit was a great devotee. the answers of his guru, Śukadeva Gosvāmī, concerning karma-kāṇḍa and jñāna-kāṇḍa could not satisfy him. Therefore Śukadeva Gosvāmī, knowing very well the heart of his disciple, explained the transcendental bliss of devotional service. The word kecit, which is used in this verse, means. "a few people but not all." Not everyone can become Kṛṣṇa conscious. As Kṛṣṇa explains in Bhagavad-gītā (7.3): manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye yatatām api siddhānāṁ kaścin māṁ vetti tattvataḥ

"Out of many thousands among men, one may endeavor for perfection, and of those who have achieved perfection, hardly one knows Me in truth." Practically no one understands Kṛṣṇa as He is, for Kṛṣṇa cannot be understood through pious activities or attainment of the most elevated speculative knowledge. Actually the highest knowledge consists of understanding Kṛṣṇa. Unintelligent men who do not understand Kṛṣṇa are grossly puffed up, thinking that they are liberated or have themselves become Kṛṣṇa or Nārāyaṇa. This is ignorance.
