Our argument, our logical, I mean to say, strength has no access in the spiritual world. The Vedic mantra says, nāyam ātmā pravacanena labhyo na medhayā na bahunā śrutena (Kaṭha Upaniṣad 1.2.23): "Atma, the supreme self, cannot be realized pravacanena." Suppose I am very expert speaker, I can present things very nicely—but without any substance. Oh, that won't help you. Simply by jugglery of words, if I can captivate you, oh, that won't help you. Nāyam ātmā pravacanena. This is pravacana.
Of course, we are delivering speeches from authoritative book, Bhagavad-gītā. I am not speaking before you of my own imagination. I am speaking from the authorized book. Therefore it is not exactly pravacana, neither I am squeezing out some meaning for my purpose. I am just presenting you the same principle. Mahājano yena gataḥ sa panthāḥ. As Lord Caitanya Mahāprabhu preached, I am trying to present the same thing before you in a different language only. That's all.
Because in India He preached in Sanskrit. He was a very learned scholar in Sanskrit. Formerly, any big man, any big scholar, they would be big scholar in Sanskrit. Sanskrit was the written language. Even in the beginning of the British period, Sanskrit was written language. It is the policy of Lord McCauley that he transformed the whole attitude. They made a plan that, "If Indians remain as Indian, then we cannot rule over. Then we cannot rule over. We must make them anglicized." So that policy was followed for two hundred years. So India has lost its original culture.
