Meek and mild, yes. So that is the qualification. You have to become humble. Therefore the Bhāgavata also says the same thing. Jñāne prayāsam. Don't be very much proud of your so-called knowledge that, "I can understand everything." You should become namra, meek and mild. And then how to be . . .? Jñāne prayāsam udapāsya namanta eva san-mukharitāṁ bhavadīya-vārtām. You should engage yourself to receive spiritual knowledge from the authority, reliable source. Spiritual knowledge is understood through the ear. Therefore the Vedas are called śruti. San-mukharitāṁ bhavadīya-vārtām. This is recommended, that Kṛṣṇa's kathā should be heard from the realized source. San-mukharitām. San means devotee. Sat. Oṁ tat sat. San-mukharitāṁ bhavadīya-vārtām.
Then sthāne sthitāḥ, you can remain in your place. It doesn't matter whether you are a brāhmaṇa or a śūdra or American or Indian or . . . it doesn't matter. You keep yourself in your position. Simply go there, where these things are discussed authoritatively, you hear. Śruti-gatām. Śruti-gatām. Śruti means the ear. You just give the aural reception of the words of realized soul. San-mukharitāṁ bhavadīya-vārtāṁ sthāne sthitāḥ śruti-gatām. You can keep yourself . . . it doesn't require that you have to change your position. Simply you have to hear from the right source.
