Therefore here it is said, bhagavān uvāca. If we take instruction from Bhaga... Why we are reading Bhagavad-gītā? That is very common practice. Because it is perfect. There is no mistake, there is no illusion, there is no cheating, there is no imperfection of the senses. Just like in the Bhagavad-gītā it is said, vedāhaṁ samatītāni: (BG 7.26) "I know everything—past, present and future." Māṁ ca veda na kaścana: "But nobody understands Me." That is our position. God knows everything. Kṛṣṇa knows everything. But we do not know what is God. That is our position. We do not know. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). Īśvara, God, Kṛṣṇa, is situated in everyone's heart. Sarvasya cāhaṁ hṛdi sanniviṣṭaḥ: (BG 15.15) "I am entered in everyone's heart." Everyone's heart—not only the human being, but also animals or anything. Aṇḍāntara-stha-paramāṇu-cayāntara-sthaṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi (Bs. 5.35) **. He is within the atom. Therefore because He is within me, within you, and within everything, He knows everything. Therefore Kṛṣṇa says, vedāhaṁ samatītāni (BG 7.26). He knows everything. So because He knows everything, therefore we have to take lesson from Bhagavān. What Bhagavān says, if we take, that is perfect knowledge.
There is a paramparā system, as it is described in the Bhagavad-gītā, Fourth Chapter: evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). So our business, Kṛṣṇa conscious people, our business is very easy. Because we don't manufacture ideas. We take the idea and the words delivered by the Supreme Person, Kṛṣṇa, or His incarnation, or His representative. His representative does not say anything which the master does not say. Representative is very easy. You can become representative of Kṛṣṇa if you do not interpret Kṛṣṇa's words in your whimsical way. Kṛṣṇa says, mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya: (BG 7.7) "There is no more superior authority than Me." And if you take it as it is, and if you speak to the people that "There is no more superior authority than Kṛṣṇa," then you become guru. You become guru. You don't change. Then you become guru. Caitanya Mahāprabhu has instructed this. Āmāra ājñāya guru hañā tāra' ei deśa (CC Madhya 7.128). His, He was preaching. So He was preaching everyone, from country to country. Of course, He did not go outside India. Within India. And He was instructing that "You learn from Me and teach your people within this village, within this country." Āmāra ājñāya guru hañā tāra' ei deśa (CC Madhya 7.128). Ei deśa means "this country, or this place where you are living." Then? Āmāra ājñāya guru hañā. You become guru. So one may think that "I am illiterate. I have no education. I am not born in very high family. How I can become guru?" So Caitanya Mahāprabhu says that "It is not very difficult." Yāre dekha tāre kaha kṛṣṇa-upadeśa (CC Madhya 7.128). Bas. You become guru. You simply speak whatever Kṛṣṇa speaks. Then you become guru.
