So Caitanya Mahāprabhu, therefore He has said, "If we are eager for advancement in Kṛṣṇa consciousness, then we can stay in any āśrama. It doesn't matter." Either gṛhastha āśrama or sannyāsa āśrama, it doesn't matter. Kṛṣṇa . . . Caitanya Mahāprabhu says to Rāmaṇanda,
- kibā vipra, kibā śūdra, nyāsī kene naya
- yei kṛṣṇa-tattva-vettā, sei 'guru' haya
- (CC Madhya 8.128)
Sei guru. Who can become guru? Generally a brāhmaṇa, a sannyāsī, that is, that is their post. Brāhmaṇa is the guru of other varṇas, and sannyāsī is the guru for all varṇāśrama. This is . . . but Caitanya Mahāprabhu says that is social system. If there is a brāhmaṇa, if there is a sannyāsī, one should accept . . . give preference to him, to accept guru. But Caitanya Mahāprabhu says, "That is not the criterion. One must be well expert, experienced, well aware of the science of Kṛṣṇa. He shall be guru." Not that particularly because one is born in a brāhmaṇa family or one has taken sannyāsa, he is immediately by the dress or by birth one can become guru. No. That is going on. Now it is diminishing. Formerly, in India it was the practice.
So Caitanya Mahāprabhu says that "It doesn't matter." Kibā vipra, kibā śūdra. Vipra means brāhmaṇa, and śūdra means the fourth class, less than the vaiśyas. So kibā vipra, kibā śūdra, nyāsī kene naya. Nyāsī means sannyāsī. Never mind nyāsī, or without nyāsī, because śūdra cannot be sannyāsī. Without becoming brāhmaṇa, there is no question of becoming sannyāsa. In the Śaṅkara-sampradāya they are very strict. Unless one is born in a brāhmaṇa family, he is not awarded the sannyāsa. That is the stricture. But according to our Vaiṣṇava, according to Caitanya Mahāprabhu, pāñcarātrikī-viddhi, if there is little tendency of a person to become devotee, he is given the chance, never mind he's born in a śūdra family, a caṇḍāla family. That is sanctioned in the śāstra: kirāta-hūṇāndhra-pulinda pulkaśā ābhīra-śumbhā yavanāḥ khasādayaḥ, ye 'nye ca pāpā (SB 2.4.18). Anyone. Kṛṣṇa also says, māṁ hi pārtha vyapāśritya ye 'pi syuḥ pāpa-yonayaḥ (BG 9.32). So Nārada Muni, he is a great devotee, he has given allowance to everyone to become a brāhmaṇa, to become a sannyāsī. First of all he must be trained up to become a brāhmaṇa, then sannyāsī. This is a fact. Without becoming a brāhmaṇa, there is no question of sannyāsa.
So these regulative principles are there. So what is . . . what is the big plan behind these regulative principle? The big plan is: here is the attraction, puṁsaḥ striyā mithunī-bhāvam—to cut down this attraction between male and female. This is the big plan. Otherwise, there is no need of the varṇāśrama. Varnāśrama means to train the candidates gradually to become free from this entanglement of man and woman. This is the basic principle. Yoga system is also the same thing. Jñānī, that is also same. Karma also. The karma-kāṇḍīya vicāra, that is also, one has to take sannyāsa at the ultimately, cātur-varṇyaṁ mayā sṛṣṭam guṇa-karma-vibhāgaśaḥ (BG 4.13), gradually, if one cannot take it immediately.
