The perfect knowledge is in the Vedas. Therefore it is advised, tad-vijñānārthaṁ gurum evābhigacchet śrotriyaṁ brahma-niṣṭham (MU 1.2.12). You should go to a guru who has complete knowledge from the śruti. Śruti means Vedas. Ācāryavān puruṣo veda (Chāndogya Upaniṣad 6.14.2). Veda means you have to approach ācārya. He knows everything—unless he is not followers of the Vedas, śruti, he's a rascal. What is the use of going there? What is the . . . What you'll get by approaching a so-called rascal guru, one who does not know śruti? Therefore Śrīla Rūpa Gosvāmī has forbidden, and Sanātana Gosvāmī has forbidden. Avaiṣṇava-mukhodgīrṇaṁ pūtaṁ hari-kathāmṛtam, śravaṇaṁ naiva kartavyam (Padma Purāṇa). Because śravaṇam, śruti . . . To go to guru means to hear from him, to inquire from him.
- tad-vijñānārthaṁ sa gurum evābhigacchet
- samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham
- (MU 1.2.12)
You have to approach such guru. And who is that guru? Vaiṣṇava. Not any ordinary person. Therefore anyone who is not Vaiṣṇava, you should not approach. It is false knowledge. Its knowledge has no value. Sanātana Gosvāmī has strictly forbidden: avaiṣṇava-mukhodgīrṇaṁ pūtaṁ hari-kathāmṛtam, śravaṇaṁ naiva kartavyam. Don't hear. You'll be spoiled. Caitanya Mahāprabhu has said, māyāvādi-bhāṣya śunile haya sarva-nāśa (CC Madhya 6.169). If you hear from a Māyāvādī, impersonalist, then your spiritual progress is doomed, finished. No more spiritual progress. Māyāvādi-bhāṣya śunile. Māyāvādī haya kṛṣṇe aparādhī. The Māyāvādī, they are offenders to Kṛṣṇa. Kṛṣṇa is the Supreme Person, and the Māyāvādī wants to make Him imperson; therefore they are offenders.
