In the Brahma-saṁhitā also it is stated, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1). There are many gods, but who is the Supreme God? The Supreme God is Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ. Paramaḥ means the Supreme. You may be your god, I may be god, and there are many gods. But Kṛṣṇa is the Supreme God. Nobody is above Him. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ anādir ādir govindaḥ. He has no cause, anādi. He is causeless. We have got cause; He is causeless. Anādir ādir govindaḥ. Govinda means He is pleasure of... He is the reservoir of all pleasure, Govinda. Anādir ādir govindaḥ sarva-kāraṇa-kāraṇam (Bs. 5.1), cause of all causes. So here it is said that "That Bhagavān, who is sātvatāṁ patiḥ..." That means there are many great, great devotees, stalwart devotees, ācāryas and teachers, and for all of them, He is the master. Sātvatāṁ patiḥ. And what is to be done about Him? śrotavyaḥ: "You have to hear about Him." Where I can hear? When He speaks Himself. Why don't you hear there? How can you know the Supreme, the cause of all causes? Nobody can explain. But when He explains Himself, you can hear. That is Bhagavad-gītā. Kṛṣṇa is explaining Himself.
Suppose if you want to know me or know something about me, you can ask some friend, "Oh, how is Swamiji?" He may say something; other may, something. But when I explain to you myself, "This is my position. I am this," that is perfect. That is perfect. So if you want to know the Absolute Supreme Personality of Godhead, you cannot speculate, neither meditate. It is not possible, because your senses are very imperfect. So what is the way? Just hear from Him. So He has kindly come to say Bhagavad-gītā. Śrotavyaḥ: "Just try to hear." Śrotavyaḥ and kīrtitavyaś ca. If you simply hear and hear in the class of Kṛṣṇa consciousness, and go outside and forget, oh, that is not nice. That will not make you improve. Then what is? Kīrtitavyaś ca: "Whatever you are hearing, you should say to others." That is perfection.
Therefore we have established Back to Godhead. The students are allowed, whatever they are hearing, they must be thoughtful and write. Kīrtitavyaś ca. Not only simply hearing. "Oh, I am hearing for millions of years; still, I cannot understand"—because you do not chant, you do not repeat what you have heard. You have to repeat. Kīrtitavyaś ca. śrotavyaḥ kīrtitavyaś ca dhyeyaḥ. And how can you write or how you can speak unless you think of Him? You are hearing about Kṛṣṇa; you have to think, then you can speak. Otherwise not. So śrotavyaḥ kīrtitavyaś ca dhyeyaḥ and pūjyaś ca. And you should worship. Therefore we require this Deity for worshiping. We have to think of, we have to speak, we have to hear, we have to worship, pūjyaś ca... Then, occasionally? No. Nityadā: regularly, regular. Nityadā, this is the process.
