na parama rohanti yathā karambha-bījāni
guṇa-gaṇato ’sya dvandva-jālāni
This is confirmed in Bhagavad-gītā (4.9), wherein the Lord says:
janma karma ca me divyam
evaṁ yo vetti tattvataḥ
tyaktvā dehaṁ punar janma
naiti mām eti so ’rjuna
“One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.” If one simply engages in Kṛṣṇa consciousness to understand Kṛṣṇa, he surely becomes immune to the process of repeated birth and death. As clearly stated in Bhagavad-gītā, tyaktvā dehaṁ punar janma naiti: such a person, simply by engaging in Kṛṣṇa consciousness or understanding the Supreme Personality of Godhead, Kṛṣṇa, becomes quite fit to return home, back to Godhead. Even those who are obsessed with material desires may also come to worship the Supreme Personality of Godhead so steadily that they go back to Godhead. The fact is that if one comes to Kṛṣṇa consciousness, although he may have many material desires, he becomes increasingly attracted to the lotus feet of Kṛṣṇa through associating with the Supreme Lord by chanting His holy name. The Supreme Lord and His holy name are identical. Thus he becomes uninterested in attachment to material enjoyment. The perfection of life is to be uninterested in material enjoyment and interested in Kṛṣṇa. If one comes to Kṛṣṇa consciousness somehow or other, even for material gain, the result is that he will be liberated. Kāmād dveṣād bhayāt snehāt. Whether for the satisfaction of material desires, because of the influence of envy, because of fear, because of affection or because of any other reason, if one comes to Kṛṣṇa, his life is successful.
