Therefore we have to consult śāstra. What is our problem, we have to consult śāstra. And śāstra, how we can consult śāstra. Śāstra, we have to go somebody who knows śāstra. Therefore the Vedic injunction is tad-vijñānārthaṁ sa gurum eva abhigacchet, śrotriyam (MU 1.2.12). If you want to know what is your actual interest, then you have to approach a guru. And who is guru? Śrotriyam, who knows śāstra. Śrotriyam. And not only knows, but the result must be there, brahma-niṣṭham, means Kṛṣṇa consciousness. Brahma-niṣṭham means fully dependent on Kṛṣṇa.
This is the process. We must know, we must find out guru who knows śāstra, the essence of śāstra, Vedic, Vedas. What is the essence of Vedas? Vedānta. Vedānta means to know Kṛṣṇa. Vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). Kṛṣṇa says. All... There are different types of Vedas. Sāma, Yajur, Ṛk, Atharva. Then one-hundred-eight Upaniṣads. Then Vedānta-sūtra. Then Purāṇas, Rāmāyaṇa, Mahābhārata. And the viṁśati, twenty kinds of dharma-śāstra, Manu-saṁhitā. So many things.
