Srimad-Bhagavatam Lectures

So we have to follow. Mahājano yena gataḥ sa panthāḥ. There we have created these GBCs. So they should be very responsible men; otherwise, they will be punished. They will be punished to become a śūdra. Although Yamarāja is a GBC, but he made a little mistake, he was punished to become a śūdra. So those who are GBC, they should be very, very careful to administer the business of ISKCON. Otherwise they will be punished. As the post is very great, similarly, the punishment is also very great. That is the difficulty.

Lecture on SB 1.13.15 -- Geneva, June 4, 1974:
So Vidura was Yamarāja. Not only he was Yamarāja, ordinary, but he is one of the great authorities. There are twelve authorities mentioned in the śāstra. One of them is Yamarāja. Balir vaiyāsakir vayam. This is stated in the Śrīmad-Bhāgavatam. Yamarāja is one of the GBC of Kṛṣṇa. Yes. As we have got twelve GBCs, similarly Kṛṣṇa has got twelve GBCs. Now:

svayambhūr nāradaḥ śambhuḥ

kapilo kumāraḥ manuḥ

prahlādo janako bhīṣmo

balir vaiyāsakir vayam

(SB 6.3.20)

That twelve men are authorized to preach Kṛṣṇa consciousness. So we have to follow. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). There we have created these GBCs. So they should be very responsible men; otherwise, they will be punished. They will be punished to become a śūdra. Although Yamarāja is a GBC, but he made a little mistake, he was punished to become a śūdra. So those who are GBC, they should be very, very careful to administer the business of ISKCON. Otherwise they will be punished. As the post is very great, similarly, the punishment is also very great. That is the difficulty. You can see from this example, Vidura. He was immediately punished. He did little mistake at Maṇḍūka . . . because the ṛṣis, the munis, they will curse. Dealing is very . . . even Yamarāja is not taking.
