Kintu prabhor yaḥ priya eva tasya. Yasya prasādād bhagavat-prasādo. By the mercy of guru, you get the mercy of Kṛṣṇa. If, if guru approves, that "Here is a nice devotee," then Kṛṣṇa accepts, "Yes, here is a nice devotee."
So therefore yasya prasādād, our business is to please guru. If he is satisfied, then Kṛṣṇa immediately becomes satisfied, because he is the agent. That is very easy to understand. Suppose you are working in office, your immediate boss the superintendent, if he is pleased, that means the managing director is also pleased. You haven't got to please the managing director separately. If you please his representative, then the managing director sees the report, "Yes this man is working nice." That he will accept. He has never seen him. But that is not the fact, Kṛṣṇa also seeing you. So this is called mad-āśritāḥ. Yuñjan..., mayy āsakta-manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ. You have to take shelter of Kṛṣṇa. And Kṛṣṇa, because you have no direct touch of Kṛṣṇa, therefore you take shelter of Kṛṣṇa's representative. Then this yuñjan begins. He will teach you how to practice the bhakti-yoga, how to worship Him, how to think of Him, how to offer obeisances, how to observe the ceremonies.
Bhagavad-gītā 7.1 , Melbourne, June 29, 1974
Anyone who is thinking that "I shall make spiritual advancement without guru," he is wrongly thinking. It is not possible. Just like if you want to see a big man, you have to go through the servant of that man. You have to take permission. The servant may say, "Sir, such-and-such man wants to see you. He is very nice man, appears to be a good man." "Oh," the master says, "he is good man? All right, bring him." By the recommendation of the servant.
Therefore we sing daily, yasya prasādād bhagavat-prasādaḥ **. By the mercy of guru, immediately we become, get the mercy of God. Yasya prasādād bhagavat-prasādo yasyāprasādān na gatiḥ kuto 'pi **. Yasyāprasādāt. By... If guru is not satisfied, then na gatiḥ kuto 'pi. He has no gati. Gati means advancement. He has no advancement. Dhyāyaṁ stuvaṁs tasya yaśas tri-sandhyam. Therefore this Gurvaṣṭaka, saṁsāra-dāvānala, we have to sing. So God's incarnation, here it is said, "There are many incarnations." So guru is also incarnation of God, mercy incarnation of God. Guru means that... God is within you, caitya-guru, the guru, or the spiritual master, within your heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati [Bg. 18.61]. So this Paramātmā is also incarnation of God. And the same Paramātmā, when He comes before you, being very much merciful upon you, to teach you from outside, that is guru. Therefore it is said, sākṣād-dharitvena samasta-śāstraiḥ. Guru is the mercy incarnation of God. Sākṣāt, direct. Hari-tvena, he is Hari, God. Samasta-śāstraiḥ. It is not that somewhere it is stated, somewhere it is not stated. No. In all Vedic literature. Sākṣād-dharitvena samasta-śāstrair uktaḥ **. Uktaḥ means "it is said." And tathā bhāvyata eva sadbhiḥ. Sadbhiḥ, those who are real devotees, they accept this. "Yes, guru is exactly representative of Kṛṣṇa, mercy representative."
Śrīmad-Bhāgavatam 1.3.26, Los Angeles, October 1, 1972
Yasya prasādād bhagavat-prasādaḥ. Śrīla Viśvanātha Cakravartī Ṭhākura, he has very much stressed on the mercy of guru. And that is actually fact. If we receive the mercy of guru, if we can satisfy guru by our service, and if he gives his blessing, that is very, very great opportunity. Yasya prasādād bhagavat-prasādaḥ. Guru is confidential servant of Kṛṣṇa. Guru never claims that he is Kṛṣṇa, he is God. That is not guru. Guru, although worshiped as Kṛṣṇa, Kṛṣṇa... Sākṣād-dharitvena samasta-śāstraiḥ. Not in one śāstra, but all the Vedic śāstra, they describe guru, guru-brahma. They describe on the equal footing. Guru, being representative of Kṛṣṇa, he is worshiped as Kṛṣṇa. Sākṣād-dharitvena samasta-śāstraiḥ. All śāstra recommends that. Tathā bhāvyata eva sadbhiḥ. And those who are pure devotees, they accept. But that does not mean that guru declares himself that "I am Kṛṣṇa. I am God." No. Kintu prabhor yaḥ priya eva tasya. He is the most confidential servant of Kṛṣṇa; therefore he is very dear. And as he is very dear to Kṛṣṇa, if he recommends somebody, "Kṛṣṇa, accept him," He will accept him. Yasya prasādād bhagavat-prasādaḥ. That is the system.
Guru is very confidential servant of Kṛṣṇa. Why confidential servant? Because he is canvassing door to door, "Please become Kṛṣṇa conscious. Please surrender to Kṛṣṇa." Kṛṣṇa says to Arjuna, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja [Bg. 18.66], and guru takes that very mission, but does not say like Kṛṣṇa, that "You surrender to me." He says, "Surrender to Kṛṣṇa." One has to surrender to Kṛṣṇa through the via media of guru, not directly. This is the process. Therefore guru accepts respects from the disciple not for his personal self, but conveying the respect to Kṛṣṇa. This is the process. Yasya prasādād bhagavat-prasādo yasyāprasādān na gatiḥ kuto 'pi. If you cannot get the mercy of guru, then it is very difficult to approach Kṛṣṇa. We cannot approach Kṛṣṇa directly. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ [Bg. 4.2]. That is the statement in the Bhagavad-gītā. Paramparā. Guru, he offers the same respect to his guru, his guru, it goes. In this way, it goes to Kṛṣṇa, paramparā. As the mercy of Kṛṣṇa comes through the paramparā system, similarly, the offering of respect to Kṛṣṇa goes up through the paramparā system. Therefore it is stated, bhavad-anugrahāt. Bhavad-anugrahāt: "Please kindly become merciful upon me."
So in this way, one has to learn how to approach the Supreme Personality of Godhead. Our Vaiṣṇava system is ādau gurv-āśrayam [Brs. 1.1.74]. If we want to approach Kṛṣṇa, then in the beginning, ādau, the beginning is to take shelter of guru.Śrīmad-Bhāgavatam 3.25.30
