Is it very difficult to be a preacher?

Is it very difficult to be a preacher? You are going to be preacher, going
to Japan? Do you think it is difficult? It is difficult? Simply say like
this:
“God is great. Don’t be puffed up that you are great, you are all-powerful,
you have got… Give up these foolish ideas. God is great. He has created
this world. He is giving you food; He has given you body.”
Just simply try to convince them, these principles, and you become a
preacher. Just try to understand. This is our philosophy, Krsna
consciousness preaching. You don’t require any high type of philosophical
speculation or this or this ism, that ism, that ism — no. Simple truth.
That’s all. Just try to glorify the Supreme Lord, the great. That’s all. And
whatever capacity you have got — not that you have to qualify yourself in
this way.
