First of all one must know what is Kṛṣṇa. That is being explained by Kṛṣṇa Himself in the Bhagavad-gītā, and when he understands what is Kṛṣṇa, then he can hear further about Kṛṣṇa. The books are there, Śrīmad-Bhāgavatam and Nectar of Devotion, Teachings of Lord Caitanya—all we are teaching the science of Kṛṣṇa. So here also Caitanya Mahāprabhu said, yei kṛṣṇa-tattva-vettā, sei 'guru' haya (CC Madhya 8.128): "Anyone who knows the science of Kṛṣṇa, he can become guru." That is our mission. That is not my mission; that is Caitanya Mahāprabhu's mission. So it doesn't matter you Europeans, Americans, although not born in brāhmaṇa family. It doesn't matter. That is Caitanya Mahāprabhu's approval. If you try to understand the science of Kṛṣṇa, then, and if you behave properly, you can teach about Kṛṣṇa all over your country, all over the world. That is my mission. And that is approved by Caitanya Mahāprabhu. Try to understand the science of Kṛṣṇa. Then you will be able to preach nicely, and people will be benefited.
So here Devahūti, (s)he is taking lesson from his (her) son. The son is given birth by the mother. She may think that "I have given birth to you. What you will teach me?" No. Because he knows the science of Kṛṣṇa. Or He is Kṛṣṇa Himself. Therefore she is taking lesson from her son, exalted son. She is very fortunate lady, Devahūti. She is addressed here, nṛpātmaje. Nṛpa means king; ātma-ja means offspring. So she was the daughter of the emperor of the higher planetary system, Manu, Vaivasvata Manu. The Vaivasvata Manu's name you have heard in the Bhagavad-gītā: imaṁ vivasvate yogaṁ proktavān aham avyayam, vivasvān manave prāhuḥ (BG 4.1). This Manu, Vaivasvata Manu, vivasvān manave prāhuḥ. The sun-god, whose name is Vivasvān, he spoke to his son, Manu. This Manu is the father of Devahūti. She is not ordinary girl. So how fortunate she was.
