It is very easy to preach and propagate Krishna Consciousness to the people of our country, because they naturally have faith and belief in god and are already god conscious. But it is not so easy to preach pure God consciousness i.e., Krishna Consciousness to the people who doesn't know what is God and how to love god. Srila Prabhupada had travelled all over the world and spread the message of Lord Krishna and wherever he went, whomever he met he made them to follow Krishna consciousness. It was a wonderful service. He was a great scholar and one of the greatest person / devotee we have ever seen.
