Srimad-Bhagavatam Lectures

The family of Kṛṣṇa, there is no power in the whole world that anybody could kill them. So Kṛṣṇa planned that they should be killed amongst themselves by fighting. So another lesson is that if we fight amongst ourselves, even we belong to the family of Kṛṣṇa, we are ruined. This is the instance of Yadu-kula. Although they belonged to Kṛṣṇa's family directly, still, because they fought amongst themselves, they were all banished, vanquished.

Lecture on SB 1.13.12 -- Geneva, June 3, 1974:

Nitāi: Translation: "Thus being questioned by Mahārāja Yudhiṣṭhira, Mahātmā Vidura gradually described everything that he had personally experienced, except the news of the annihilation of the Yadu dynasty."

Prabhupāda:

ity ukto dharma-rājena

sarvaṁ tat samavarṇayat

yathānubhūtaṁ kramaśo

vinā yadu-kula-kṣayam

(SB 1.13.12)

Yadu-kula-kṣayam. The Yadu dynasty . . . when Kṛṣṇa was present, the family members were about ten millions. This is Kṛṣṇa. Everything is wonderful. He married 16,108 wives, and each wife had ten children, and each child begot another ten children. In this way, the Yadu-kula was a very big family. So they were destroyed.

There are two comments on this point, why Yadu-kula was destroyed by Kṛṣṇa plan. One comment is that if they would continue to live, then the same misconception, that a brāhmaṇa is born in the brāhmaṇa family, they would continue to speak that, "We are also gods, because we are born of God's family, Kṛṣṇa's family." Just like in India there is a class, they call themselves Nityānanda-vaṁśa, descendants of Lord Nityānanda. But that does not actually happen. And another comment is that all these members of Yadu-kula, they appeared in the Yadu-kula just to enhance the opulence of Kṛṣṇa. But they came from different heavenly planets to help Kṛṣṇa in His incarnation. Just like a big man, wherever he goes there are many others also go there to help him. When a king goes somewhere, the king does not go alone. He goes with his secretaries, his military commanders, and so many other companions.

So these Yadu-kulas were like that. They came to help Kṛṣṇa's līlā, pastimes, within this material world. So some of them were born as sons of Kṛṣṇa, some of them as grandson, as great-grandson, and Kṛṣṇa did not want to leave them behind. Kṛṣṇa was planning to go back to His Vaikuṇṭha here, Vṛndāvana planet. So He did not like that they should remain. They should also go back. Now, to go back means they must meet death after . . . because otherwise it is unnatural. So . . . and who can kill them? Nobody can kill them. That is also another point. The family of Kṛṣṇa, there is no power in the whole world that anybody could kill them. So Kṛṣṇa planned that they should be killed amongst themselves by fighting. So another lesson is that if we fight amongst ourselves, even we belong to the family of Kṛṣṇa, we are ruined. This is the instance of Yadu-kula. Although they belonged to Kṛṣṇa's family directly, still, because they fought amongst themselves, they were all banished, vanquished.

So this was not a very palatable incidence. So Vidura, when he was asked by Mahārāja Yudhiṣṭhira about the family members of Yadu-kula, he did not describe it, because they were very thickly related as family members, so it would be a great shock to the Pāṇḍavas that Yadu-kula, descendants of the Yadu-kula, had been annihilated in such an unpalatable way. So he did not describe. Yathānubhūtaṁ kramaśaḥ. Ity ukto dharma-rājena sarvaṁ tat samavarṇayat. He described everything. Vinā yadu-kula-kṣayam. Vinā. Vinā means "without," without the incidence, how the Yadu-kula was destroyed by fighting amongst themselves.

nanv apriyaṁ durviṣahaṁ

nṛṇāṁ svayam upasthitam

nāvedayat sakaruṇo

duḥkhitān draṣṭum akṣamaḥ

(SB 1.13.13)

He did not describe because he did not like also to see that Pāṇḍavas would be sorry. He went back to his home after so many years, and they were receiving them, and at that time Vidura did not like to see them aggrieved on account of this incidence.

kañcit kālam athāvātsīt

sat-kṛto devavat sukham

bhrātur jyeṣṭhasya śreyas-kṛt

sarveṣāṁ sukham āvahan

(SB 1.13.14)

Vidura left his home for good. It is not that he has again come back to live with his family members. No. His only purpose was that his elder brother Dhṛtarāṣṭra was rotting there. He lost everything. He lost his kingdom, lost his sons, grandsons and everything. Still he could not give up the so-called material happiness. He was . . . of course, these Pāṇḍavas, they were treating Mahārāja Dhṛtarāṣṭra and his wife Gāndhārī very gorgeously as head of the family, but he was not ashamed that he intrigued so much difficulties and plot against the Pāṇḍavas. There was big fight, Kurukṣetra, in which he lost everything. Still he was living under their care for some material comforts. So this was very shameful affair. So Vidura was very much attracted, attached to Mahārāja Dhṛtarāṣṭra. Therefore, bhrātur jyeṣṭhasya śreyas-kṛt. Bhrātuḥ means brother, and jyeṣṭha means elder. So actually, Vidura went there for the benefit of Dhṛtarāṣṭra. Therefore, kañcit kālam atha avātsīt. He decided to live at home along with the family members for some time.
