Caitanya Mahāprabhu is stressing that to read Vedic literature, Vedānta, Upaniṣad—these are principal literatures in the Vedic knowledge—then Bhagavad-gītā, Śrīmad-Bhāgavatam, all these books should be studied from the direct meaning. Don't try to interpret. According to ordinary, I mean to say, dealings, suppose in the law court there are two parties. Two lawyers are fighting on the principle of one clause or section in the law book. One is interpreting in a different way, one is interpreting in a different way, and the judges give their judgment.
Now, the opportunity for interpretation is there when the meaning is not clear. A very good example is given by the grammarians, or Sanskrit scholar, that gaṅgayaṁ ghoṣapali that, "There is a neighborhood which is called Ghoṣapali on the Ganges." Now somebody may ask, "How there can be a quarter on the Ganges? Ganges is water." So there is interpretation required. So somebody says: " 'On the Ganges' means on the bank of the Ganges." That makes it clear. "On the Ganges" does not mean that in the middle water there is a, I mean to say, residential quarter. No. "On the Ganges" means on the bank of the Ganges.
So when there is such doubt, one can interpret. But when there is no doubt—everyone can understand clearly the meaning—there is no question of interpreting. That is Caitanya Mahāprabhu's stressing, that gauṇa-vṛttye yebā bhāṣya karila ācārya (CC Adi 7.109). Therefore each and every aphorism and verse of Vedānta-sūtra has been indirectly interpreted by the Śārīraka-bhāṣya. Such interpretation, if somebody hears, then his future is doomed.
