Srimad-Bhagavatam Lectures

The first guru. Guru, agni, arka—means sun—and then God. Therefore you see in our Deity room there is picture of guru first of all. First of all your guru, then his guru, then his guru—at least four, five generation, because the spiritual knowledge is received through the paramparā. I have received from my guru; you are receiving from your guru; and my guru received from his guru; he received his guru.

Lecture on SB 7.12.2 -- Bombay, April 13, 1976:

So the first teaching is brahmacārī should rise early in the morning. Brahmacārī . . . That is the general education. It doesn't require that you have to learn some book immediately. No. First of all build your character. Otherwise what is the use of taking degrees if you have no character? Yasyāsti bhaktir bhagavaty akiñcanā sarvair guṇair tatra samāsate surāḥ (SB 5.18.12). If you become a devotee of Kṛṣṇa . . . Just like in our institution they are being trained up as devotee, so to rise early in the morning is automatically there. There is no separate training. Because he is devotee, he has to rise early in the morning for offering maṅgala-āratika, and you have got our order that everyone must attend the maṅgala-ārati. That is automatically, brahmacārī. Sāyaṁ prātar upāsita. And what is the upāsana? The first, guru. Guru, agni, arka—means sun—and then God. Therefore you see in our Deity room there is picture of guru first of all. First of all your guru, then his guru, then his guru—at least four, five generation. Because the spiritual knowledge is received through the paramparā. I have received from my guru; you are receiving from your guru; and my guru received from his guru; he received his guru. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). Ādau gurvāśrayam (Bhakti-rasamrta-sindhu). You cannot learn to become a perfect human being without accepting guru. Then you remain a rascal. Tad-vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). That is the Vedic injunction. If you want to learn that transcendental science, you must approach a guru. Guru principle is the same, not that your guru and my guru will be different. If he is actually guru, then there is no difference between my guru and your guru. Just like a medical man. You consult one medical man; I consult another. That does not mean the medical man is different. They are depending on the same medical science. So guru means the following the same principles. Evam paramparā-prāptam (BG 4.2). The first guru is Kṛṣṇa, the supreme guru. He is the guru of Brahmā even. Brahmā is the first creature of this universe. Tene brahma hṛdā ādi-kavaye muhyanti yatra sūrayaḥ (SB 1.1.1). So Kṛṣṇa is the original guru. Then Kṛṣṇa spoke to the sun god, imaṁ vivasvate yogaṁ proktavān aham (BG 4.1).
