So a human life should be engaged inquiring about the Absolute Truth, and he should inquire from a person who . . . who has heard about the Absolute Truth from a realized person. This is a . . . therefore it is called śruti, paramparā, disciplic succession. One . . . just like Vyāsadeva is hearing from Nārada. Nārada is authorized. He has heard from Brahmā. Brahmā has heard from Kṛṣṇa. So this is the paramparā system, disciplic succession.
So there are four paramparā systems. They are known as, at the present moment, Rāmānuja-sampradāya, Brahmā-sampra . . . Brahmā-samprada . . . yes, Madhva-sampradāya, Brahmā-sampradāya, Madhva-sampradāya, the same, and Rudra-sampradāya and Śrī-samp . . . Śrī, Rāma, Kumāra-sampradāya. There is four sampradāyas. So we should hear from the sampradāya-ācārya by disciplic succession. As Kṛṣṇa recommends in this Bhagavad-gītā: evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2).
- imaṁ vivasvate yogaṁ
- proktavān aham avyayam
- vivasvān manave prāha
- manur ikṣvākave 'bravīt
- (BG 4.1)
Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ. So that is the system. We should receive knowledge by the bona fide, paramparā system. Otherwise it may be bogus. Because without paramparā system, we cannot understand actual fact. And we have to become in the disciplic succession. We must accept a guru. Tasmād guruṁ prapadyeta jijñāsuḥ śreya uttamam (SB 11.3.21). If you are actually eager, anxious to understand the spiritual science, then you must approach a guru. Tasmād guruṁ prapadyeta jijñāsuḥ śreya uttamam.
Uttama means transcendental subject matter. You cannot learn it. Just like if you purchase one pharmacology book from the bookseller's shop, and if you read, at home, do you mean that you become a medical practitioner, pharmacist? No. You must go to the university, you must go to the college. You must hear the experienced professor and learn it and practically experiment it. Then you can learn. Not that by purchasing a book you become a medical practitioner or lawyer. That is not possible. Therefore the direction is that tad-vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12): "Must."
Here also we see, Kṛṣṇa in the beginning was talking with Arjuna just like friends. But when Arjuna understood it that, "We are talking like friends, so we cannot come into conclusion . . ." The friend, they talk, they argue, they put logic. In that way, we cannot understand. Na tāṁs tarkeṇa yojayet. Then? Tad-vijñānārthaṁ sa gurum eva abhigacchet. So therefore Arjuna surrendered himself: śiṣyas te 'haṁ śādhi māṁ prapannam (BG 2.7).
Kārpaṇya-doṣopahata-svabhāvaḥ. "I, I can understand that I am a kṣatriya. It is my duty to fight. But in front of my grandfather and relatives, I am declining to fight. Therefore I am affected with kārpaṇya-doṣa. I am deviating from my duty. So why I am deviating from this duty? Therefore I am surrendering myself unto You."
