Bhagavad-gita As It Is Lectures

They're sādhu guru śāstra. And śāstra means the statement of authorities. That is śāstra. Just like Bhagavad-gītā: it is śāstra because it is spoken by the supreme guru, Kṛṣṇa. So who is guru? At the present moment so many unauthorized persons are presenting themselves as guru. But you should be very careful. Guru, Caitanya Mahāprabhu has said, āmāra ājñāya guru hañā tāra' ei deśa (CC Madhya 7.128).

So this Kṛṣṇa consciousness movement is giving chance to everyone to hear from the authoritative sources, from the śāstra. Sādhu śāstra guru. These are authorities. So instead of hearing from the unauthorized persons, means . . . sādhu means who speaks on the basis of śāstra. Guru means who speaks on the basis of śāstra. They're sādhu guru śāstra. And śāstra means the statement of authorities. That is śāstra. Just like Bhagavad-gītā: it is śāstra because it is spoken by the supreme guru, Kṛṣṇa. So who is guru? At the present moment so many unauthorized persons are presenting themselves as guru. But you should be very careful. Guru, Caitanya Mahāprabhu has said, āmāra ājñāya guru hañā tāra' ei deśa (CC Madhya 7.128). He says that "I order you that you become guru. So. and your business is to deliver this country." "This country" means wherever you are living, you can become guru and deliver them. And one may say that "You are asking me to become guru, but I have no qualification." A sincere man will say like that: "How can I become guru, and how can I deliver this country?" Caitanya Mahāprabhu says it is not difficult: yāre dekha tāre kaha kṛṣṇa-upadeśa (CC Madhya 7.128). Kṛṣṇa-upadeśa, there are two kṛṣṇa-upadeśa. One kṛṣṇa-upadeśa is what Kṛṣṇa is speaking personally, Bhagavad-gītā; and the other kṛṣṇa-upadeśa, what Vyāsadeva is speaking about Kṛṣṇa. Kṛṣṇa sa upadeśa or kṛṣṇena upadeśa. Kṛṣṇena upadeśa—Bhagavad-gītā. And instruction about Kṛṣṇa is Śrīmad-Bhāgavatam.
