Lectures : Bhagavad-gita 4.1 -- , March 21, 1974
So this is... Those who are in Kṛṣṇa consciousness, those who have decided to serve Kṛṣṇa only, they are no longer in the categories of sva-dharma, the bodily sva-dharma, brāhmaṇa, kṣatriya, vaiśya, śūdra, or brahmacārī, vānaprastha. He is transcendental. That is confirmed in every śāstra. So so far we are concerned, Kṛṣṇa conscious, so long our bodily concept of life is not completely eradicated, we must follow the sva-dharma of the body. Brāhmaṇa, kṣatriya, vaiśya, śūdra, ity ādi. But when actually advanced, that is mahā-bhāgavata. We should not imitate that, but our process is the more we advance in Kṛṣṇa consciousness, we become transcendental to this bodily concept of life, brāhmaṇa, kṣatriya, vaiśya, śūdra.
So anyone who engages himself without any reservation to the service of the Lord, he is not within the category of these eight varṇāśrama-dharma. He's transcendental. Sa brahma-bhūyāya kalpate. So as a Kṛṣṇa consciousness person, he can act like anything by the order of Kṛṣṇa. He can act as a brāhmaṇa, he can act as a śūdra, because his main business is to carry out Kṛṣṇa's order. He's no longer within the category of this sva-dharma.
Lectures : Bhagavad-gita 2.31 -- , September 1, 1973
"Prabhupāda: "I am not a brāhmaṇa, I am not a kṣatriya, I am not a kṣatriya, I am not a śūdra. I am not a brahmacārī, I am not a gṛhastha, I am not a vānaprastha..." Because our Vedic civilization is based on varṇa and āśrama. So Caitanya Mahāprabhu denied all these things: "I do not belong to any one of these." Then what is Your position? Gopī-bhartuḥ pada-kamalayor dāsa-dāsānudāsaḥ: [Cc. Madhya 13.80] "I am eternally servant of the maintainer of the gopīs." That means Kṛṣṇa. And He preached: jīvera svarūpa haya nitya-kṛṣṇa-dāsa [Cc. Madhya 20.108-109]. That is our identification. We are eternal servant of Kṛṣṇa."
