These demons, they are preaching Bhagavad-gita without Krsna. Nobody preaches about Krsna. Nobody says what Krsna wants. Sarva-dharman parityajya. Krsna wants this, but they are misinterpreting in different ways and diverting the attention of the people most foolishly, that… In the Bhagavad-gita Krsna is the center. So this is going on. You know, you are coming all from foreign countries. Bhagavad-gita is popular in your country, at least amongst the scholars and theosophists and theologists. Going on, for the last two hundred years at least. But nobody understood Krsna. That is the difference. Now for the last, say, five or ten years, because we are presenting Krsna as it is, it has become very easy for you to accept it. Unadulterated Krsna. Before this, everything was presented adulterated. Therefore there was no effect.

So if you push on this movement, unadulterated Krsna, it will go on. It will go on. And as soon as you adulterate Krsna, it will not go on. It will not be effective. You may be very good scholar or very good politician or this or that, but you'll never understand what is Krsna. Naham prakasah sarvasya yoga-maya-samavrtah [Bg. 7.25]. If you want to pollute Krsna, Krsna will never be revealed to you.
