Prabhupāda: Our superior authority, our spiritual master, he ordered me that, "You just try to preach this gospel, whatever you have learned from me, in English." So we have tried it. That's all. It is not that I am very much qualified. The only qualification is that I have tried to execute the order of superior authority. That's all. This is the secret of success.
bahu-śākhā hy anantāś ca
Bahu-śākhā hy anantāś ca. Vyavasāyātmikā-buddhiḥ, niścayātmikā-buddhiḥ. If one has got unflinching faith in Kṛṣṇa and guru, guru-kṛṣṇa-kṛpāya... (CC Madhya 19.151). We have to receive mercy both from the spiritual master and Kṛṣṇa. We cannot jump over to Kṛṣṇa. That is another nonsense. We must approach Kṛṣṇa through guru. That is paramparā system. Kṛṣṇa is not so cheap thing that you can jump over. Somebody says: "Oh, why shall I accept guru? I can approach Kṛṣṇa directly." No. Kṛṣṇa does not accept such... mad-bhaktaḥ pūjābhyadhikaḥ. Kṛṣṇa says that, "First of all you become devotee of My devotee." Caitanya Mahāprabhu says, gopī-bhartuḥ pada-kamalayor dāsa-dāsa-dāsānudāsaḥ (CC Madhya 13.80): "I am the servant of the servant of the servant of Kṛṣṇa." This is called paramparā system.
You have to learn how to become servant of the servant of Kṛṣṇa. The more you become in the lower position—servant, servant, servant, servant, servant, hundred times servant's servant—then more you are advanced. Here in this material world everyone is trying to be master of the master. Just opposite. And the spiritual world, the endeavor is to become servant's servant. This is the secret.

This is Vedic instruction.
So Viśvanātha Cakravartī Ṭhākura, in connection with the verse vyavasāyātmikā-buddhir ekeha kuru-nandana... (BG 2.41). Niścayātmikā-buddhiḥ. So Viśvanātha Cakravartī Ṭhākura says that, "The instruction which I have received from my spiritual master, that is my life and soul." This is called niścayātmikā-buddhiḥ, means assurance: "Whatever I have received, the order from my spiritual master, that will give me salvation." Or even no salvation. It doesn't matter. A real devotee, a servant, does not expect anything, but kāryam: "It is my duty. It is my duty." If one takes in such spirit... Anāśritaḥ karma-phalaṁ kāryaṁ karma karoti yā (BG 6.1). Kāryam. Kāryam means "It is my duty. It must be done. That's my duty." Without any result.
