So Caitanya Mahāprabhu... And Rāmānanda Rāya, he was also a śūdra, and he was a householder and a politician, governor, but Caitanya Mahāprabhu took instruction from him. Caitanya Mahāprabhu gave him the preference of being a teacher. He was hesitating. Rāmānanda Rāya was hesitating, "Oh, Sir, You are sannyāsī, in the highest stage of āśrama, and You, in Your previous life You belonged to the brāhmaṇa sect. So You belong to the highest class, and I am a śūdra, I am householder, and I am a politician. So how lower I am in comparison to You? And You are taking instruction from me, so I am feeling hesitation." Caitanya Mahāprabhu said, "No, no. You don't feel hesitation." He enunciated,
- kibā śūdra kibā vipra nyāsī kene naya
- yei kṛṣṇa-tattva-vettā sei guru haya
- (CC Madhya 8.128)
"Never mind a man, whatever he is. He may be a laborer class, he may be a brāhmaṇa, or he may be a sannyāsī, or he may be a householder. It doesn't matter. Anyone who knows the science of Kṛṣṇa, he is spiritual master. Anyone."
