Ahaṁ hi sarvasya prabhavaḥ (BG 10.8): "I am the origin of everything." Janmādy asya yataḥ (SB 1.1.1), the Vedānta-sūtra. "Kṛṣṇa, Brahman, Para-brahman—He is the origin of everything." Vāsudevaḥ sarvam iti (BG 7.19). One must know it. Vāsudevaḥ sarvam iti sa mahātmā sudurlabhaḥ. These things are there.
Therefore kṛṣṇe parama. The life, success of life, means how you can awaken your love for Kṛṣṇa. Kṛṣṇe parama-pūruṣe. Parama-pūruṣe, that is explained in the Caitanya-caritāmṛta: nitya-siddha kṛṣṇa-bhakti sādhya kabhu naya (CC Madhya 22.107). It is not artificially awakened. There is, already, nitya-siddha. As we are nitya-siddha . . . Nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). We are nitya; similarly kṛṣṇa-bhakti is also nitya. Kṛṣṇa consciousness is there along with the living entity; it is not an artificial thing. Just like sugar—sweetness is already there. It is the nature of sugar. It is not an artificial thing. Sugar means sweetness. Living entity means kṛṣṇa-bhakta. If he's not kṛṣṇa-bhakta, he's a rascal. Therefore Kṛṣṇa said, na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ (BG 7.15). Those who are narādhamas, lowest of the mankind, they do not become kṛṣṇa-bhakta. They become other. Therefore they are duṣkṛtina. Why they are not kṛṣṇa-bhakta? Duṣkṛtina, full of sinful activity.
So you cannot become kṛṣṇa-bhakta and indulge at the same time in sinful activities. Then it will be spoiled. You must be very careful. We have selected, summarized, the essence of sinful activities is illicit sex, meat-eating, intoxication and gambling. This is the essence. If you save yourself from these four principles, then you become sinless. And unless you become sinless, there is no question of kṛṣṇa-bhakta. Rest assured.
- yeṣāṁ tv anta-gataṁ pāpaṁ
- janānāṁ puṇya-karmaṇām

- bhajante māṁ dṛḍha-vratāḥ
- (BG 7.28)
One can be strictly engaged in Kṛṣṇa consciousness when he's free from all sinful activity. Otherwise not possible. Of course, Kṛṣṇa is very kind. If you are engaged in kṛṣṇa-bhakti sincerely, if by mistake you commit some sin, that can be excused. But if you purposefully commit sinful activities, you'll never get Kṛṣṇa's approach.
