So here Kṛṣṇa Caitanya and Nityānanda, Their identification is Lord Kṛṣṇa and Balarāma. Now, in the Kṛṣṇa incarnation, these two brothers were engaged as cowherds boy and friends of the gopīs, sons of Mother Yaśodā and Nanda Mahārāja. That is actual life in Vṛndāvana. Kṛṣṇa and Balarāma, They are village cowherds boy. That is the early age history of Kṛṣṇa-Balarāma. And Their another business, when They went to Mathurā, They killed Kaṁsa and the wrestlers, and then again, when They went to Dvārakā, They had to fight with so many demons. But Their childhood life, up to sixteenth year, They were in Vṛndāvana, happy life, simply love. That is paritrāṇāya sādhūnām (BG 4.8). Sādhus, devotees, they are always anxious to see Kṛṣṇa, Balarāma and Their associates. They are always very much aggrieved on account of separation. To give them rejuvenation of life, Kṛṣṇa-Balarāma play Their childhood days in Vṛndāvana. And out of Vṛndāvana, beginning from Mathurā up to Dvārakā and other places, the business was vināśāya ca duṣkṛtām: killing. So They have got two businesses: one for pacifying the devotees, and the other is to kill the demons. Of course, Kṛṣṇa and Balarāma, They are Absolute Truth. There is no difference between killing and loving. They... Absolute. Those who were killed, you know, they were also delivered from this material bondage.
Now these same two brothers have again descended, as Śrī Kṛṣṇa Caitanya-Nityānanda. Sahoditau: simultaneously They have appeared. Not that one is appeared, another is not there. No. Both of Them, sahoditau. And They are compared with the sun and moon. The business of sun and moon is to dissipate darkness. The sun rises during daytime, and the moon rises at night. But this sun and moon, wonderful sun and moon, citrau, They have appeared together. But the business is the same, tamo-nudau. Business is to dissipate darkness, because we are in darkness. We, anyone who is in this material world, he's in darkness. Darkness means ignorant, no knowledge. They are mostly animals. "Why they are animals, so civilized men, so well dressed and university education degrees? Why they are in darkness?" Yes, they are in darkness. "What is the proof?" The proof is that they are not Kṛṣṇa conscious. This is the proof. That is their darkness. Ask anybody, item by item, that... Ask, what do they know about Kṛṣṇa. Everyone is ignorant, dark. So that is the proof. How this is proof? Now, Kṛṣṇa says. We do not say; Kṛṣṇa says. How does He say? Na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ, māyayāpahṛta-jñānā (BG 7.15). Apahṛta-jñānā means that although they have got university degrees, although they are called civilized, advanced in material civilization, but māyayāpahṛta-jñānā. Their degrees, because they do not know Kṛṣṇa thoroughly and therefore do not surrender to Kṛṣṇa, which Kṛṣṇa is canvassing personally, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja... (BG 18.66). He's personally canvassing. Because these rascals and fools, they are in darkness—they do not know what is the goal of life—Kṛṣṇa is so kind that He is canvassing, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja. This is the philosophy. So still they are not doing so. Why? Narādhamāḥ. Because the lowest of the mankind, narādhama. How they have become narādhama? Now, duṣkṛtina, always committing sinful life. What is sinful life? Illicit sex, meat-eating, intoxication and gambling. Because they are addicted to these things they are duṣkṛtina and narādhama, lowest of the mankind. And whatever knowledge they are acquiring by so-called education, that is false knowledge. Māyayāpahṛta-jñānā. This is the position.
