Srila Prabhupada: ….Therefore we are presenting Bhagavad-gita as it is. We do not change. We have no power to change. Then where is the authority of Bhagavad-gita? I am a third-class man, and if I change the statements in the Bhagavad-gita, then where is the authority of Bhagavad-gita? That is going on. Therefore it is practically… You have got experience that there are hundreds of Bhagavad-gita editions in the Western countries, but because we are presenting Bhagavad-gita as it is, our sale is better than all others. There is a report from the trade manager of Macmillan. He says, "While other editions are dwindling, going down, this edition is coming up.
They published our, this present enlarged edition of Bhagavad-gita, fifty thousand in the month of August. They are going to print again, second edition, August, September, October. So the reason is that if we present things as they are, it will be accepted. Without any adulteration. Sometimes, you know, people say that I have done miracles. They say everywhere. But I do not know anything, miracles or magic. If there is any miracle, that miracle is that we present things as they are. That's all. Without any adulteration. So that should be the principle. Present as it is. It will be accepted.
