just present what is heard, don't become overintelligent

....our business is just to present whatever we have heard. This is very
important point. And because we do not speculate mentally, just like so many
svamis comes from India. They make their own presentation by speculation. So
whatever little success I have got, it is due to this process, that I do not
present anything which is created by me. That is the secret of success. All
these rascals, I say, declare in this, all these rascals come, they
manufacture. A spiritual thing cannot be manufactured -- as God cannot be
manufactured. God is always God, and the words of God is also God. If we
present as it is, then it will be effective. That is said in the sastra:

satam prasangan mama virya-samvido
bhavanti hrt-karna-rasayanah kathah
taj-josanad asv apavarga-vartmani
sraddha bhaktir ratir anukramisyati
[SB 3.25.25]

Everything is there. Satam prasangan. From a bona fide spiritual master you
receive knowledge, because he will present as he has received from his
spiritual master. He'll not adulterate or manufacture something. That is the
bona fide spiritual master. And that is very easy. To become spiritual
master is not very difficult thing. You'll have to become spiritual master.
You, all my disciples, everyone should become spiritual master. It is not
difficult. It is difficult when you anufacture something. But if you simply
present whatever you have heard from your spiritual master, it is very easy.
If you want to become overintelligent, to present something, to interpret
something, whatever over you have heard from spiritual master you can make
some further addition, alteration, then you'll spoil whole thing. Then
you'll spoil whole thing. Don't make addition or alteration. Simply present
as it is. Therefore, we have begun Bhagavad-gita As It Is. Don't try to
become over spiritual master. Then you'll spoil. Remain always a servant of
your spiritual master and present the thing as you have heard. You'll be
spiritual master. This is secret. You should know it. Don't try to become
overintelligent. That will spoil.
