To become guru is very difficult job, but if you simply carry the message of Bhagavad-gītā and try to convince anyone you meet, then you become a guru.

This Krishna consciousness movement is meant for this purpose. We are presenting Bhagavad-gītā as it is, without any malinterpretation. If we interpret Bhagavad-gītā in our own way, that is not very good. If you have got a different opinion, you can preach your philosophy. Everyone is free. But one should not take Bhagavad-gītā and through Bhagavad-gītā try to preach your own philosophy. That is very bad. You should not do that. Then the authority of Bhagavad-gītā is lost. If everyone can interpret in his own way, then where is the authority of the Bhagavad-gītā? Just like in the Vedas… We take Vedas as the authority. But if you interpret in your own way and squeeze out some meaning in your own way, then where is authority of the Vedas? So our special stress on this point is that don’t squeeze out some meaning of Bhagavad-gītā for your own convenience. Present Bhagavad-gītā as it is, and people will be benefited. And that is being practically seen. We are preaching Bhagavad-gītā as it is.
