Naṣṭa-prāyeṣu abhadreṣu. Finish all contamination, dirty things, and become completely pure. Because Kṛṣṇa is paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (BG 10.12). He's complete pure. Apāpa-viddham. In the Īśopaniṣad: Kṛṣṇa is uncontaminated, complete. Any contaminated thing goes to Kṛṣṇa, He makes purified. Just like the gopīs. Actually they approached Kṛṣṇa in a lusty attitude, but because He was Kṛṣṇa, He . . . they become purified.
So it is not that we shall purposefully remain impure and approach Kṛṣṇa, but the process is that if you regularly hear about Kṛṣṇa and serve Śrīmad-Bhāgavatam or a devotee, then gradually your contaminated things being washed off, bhagavaty uttama-śloke bhaktir bhavati naiṣṭhikī (SB 1.2.18). The result will be bhagavati, the Supreme Personality of Godhead, who is glorified by uttama-śloka, by transcendental prayers.
Just like Brahmā-saṁhitā. This is not ordinary words. All Vedic words, they are not ordinary, mundane words. Just like Hare Kṛṣṇa mantra. This is not mundane sound. This is transcendental sound. Golokera prema-dhana hari-nāma-saṅkīrtana. Hari-nāma-saṅkīrtana is not a, a, mean, a material sound. Therefore it is effective. But if you contaminate it, it will not be effective. If you take it, Bhāga . . . hari-nāma, purely, without any offense—there are ten kinds of offenses—then it will act immediately. Immediately it will act.
- golokera prema-dhana, hari-nāma-saṅkīrtana
- rati nā janmilo kene tāy
- biṣāya-biṣānale, dibā-niśi hiyā jvale
- tori vani nā koinu upāy
So this is the upāya. If we actually serious to get out of these material clutches, then we should hear regularly about Kṛṣṇa from a pure devotee of Kṛṣṇa. Nityaṁ bhāgavata-sevayā (SB 1.2.18). Then bhagavaty uttama-śloke bhaktir bhavati naiṣṭhikī, then your firm, steady, steadiness in devotional service will be fixed up. Bhakti . . . naiṣṭhikī. Naiṣṭhikī means nobody can, I mean, push out of it. That is naiṣṭhikī, niṣṭhā, firm faith, dṛḍha-vrata.
