So my senses, my speculative power may be greater than you, and another person's speculative power may be greater than me, but nobody can... Here it is clearly stated, na me sura-gaṇāḥ viduḥ. What you are? You are human being. Even the sura-gaṇāḥ and the great sages, they cannot. Therefore the Brahmā says that jñāne prayāsam udapāsya. Give up this process of so-called knowledge, researching, speculation. Give up this. Udapāsya, udapāsya means throw it away. Jñāne prayāsam udapāsya namanta eva. Namanta means just become submissive. Just acknowledge yourself that your senses are limited. You are subordinate even to the material nature and what to think of God? Everyone is subordinate to the control of the Supreme Lord. Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10). Nobody can be equal or greater than God. Therefore your qualification should be: be submissive. Don't waste your time in speculating. Be submissive.
Jñāne prayāsam udapāsya namanta eva and san-mukharitāṁ bhavadīya-vārtām. San-mukharitām means just try to hear about the glories of the Supreme Lord from the mouth of realized souls. Don't go to the unauthorized persons. Now, how you can know what is the difference between unauthorized and authorized? That you can know also. There is description. That, in Bhagavad-gītā you'll see, who is authorized, who is not authorized. The Lord says, evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). This authority is handed over by disciplic succession.
