As soon as you study Bhagavad-gītā by your academic knowledge, without reference to the authoritative description, then you commit mistake; you do not understand what is Bhagavad-gītā. Kṛṣṇa says, therefore that, "This disciplic succession is now broken. I therefore establish again the disciplic succession unto you." That means Arjuna becomes the disciple of Kṛṣṇa, and anyone who understands Bhagavad-gītā, following the footprints of Arjuna, he can understand rightly what is the purpose of Bhagavad-gītā.
So all Vedic literature, not only Bhagavad-gītā, all the Vedas . . . there are four Vedas: Sāma, Yajur, Ṛg, Atharva. Then there are Upaniṣads, 108 Upaniṣads. Out of that, nine Upaniṣads are very important: Īśopaniṣad, Kaṭha Upaniṣad, Taittirīya Upaniṣad. So then again, Vedānta-sūtra, then Śrīmad-Bhāgavatam.
In this way there are various Vedic literatures. And if you are interested . . . you should be interested. These Vedic literatures are not meant for a particular class of men. It was meant for the human society, so that they may take advantage of this knowledge and make a perfection of their human life.
So I shall try to speak before you this evening one of the instruction of Vedic literature spoken by Ṛṣabhadeva. So our offering of obeisances to the spiritual master is in accordance with the disciplic succession. Ajñāna-timirāndhasya jñānāñjana-śalākayā, cakṣur-unmīlitaṁ yena (Gautamīya Tantra). "The personality who opens the eyes by the torch of knowledge." Tasmai śrī-gurave namaḥ: "I offer my respectful obeisances unto the spiritual master." So here is a speech by Ṛṣabhadeva.
