Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 38

Sanskrit:

इत्युत्तानपद: पुत्रो ध्रुव: कृष्णपरायण: ।अभूत्‍त्रयाणां लोकानां चूडामणिरिवामल: ॥ ३८ ॥

ITRANS:

ity uttānapadaḥ putrodhruvaḥ kṛṣṇa-parāyaṇaḥabhūt trayāṇāṁ lokānāṁcūḍā-maṇir ivāmalaḥ

Translation:

In this way, the fully Kṛṣṇa conscious Dhruva Mahārāja, the exalted son of Mahārāja Uttānapāda, attained the summit of the three statuses of planetary systems.

Purport:

The exact Sanskrit terminology for Kṛṣṇa consciousness is here mentioned: kṛṣṇa-parāyaṇaḥ. Parāyaṇa means “going forward.” Anyone who is going forward to the goal of Kṛṣṇa is called kṛṣṇa-parāyaṇa, or fully Kṛṣṇa conscious. The example of Dhruva Mahārāja indicates that every Kṛṣṇa conscious person can expect to reach the topmost summit of all three planetary systems within the universe. A Kṛṣṇa conscious person can occupy an exalted position beyond the imagination of any ambitious materialist.
