Krishna will give you the necessary strength

By Krishna's Grace, everything is gradually coming to the fulfillment of
my dream. The Sankirtana party is walking in the streets and is getting good
response from the public. They are selling Back To Godhead nicely, and
getting good sympathy from the public by considerable collections. We are
not after collecting money, but when people offer something out of love and
sympathy for our mission, it becomes a great asset. I am sure if all my
beloved disciples combined together try to preach Krishna Consciousness in
this spirit, Krishna will give the necessary strength. By the Grace of
Krishna and the Spiritual Master, the dumb man can speak like a great
orator, and a lame man can cross over a great mountain. So we must have the
necessary unflinching faith in Krishna and the Spiritual Master, and the
strength will be supplied by Krishna. After all, anything which we
experience is but a fraction of the unlimited energy of Krishna. And even by
a fragmental touch of such spiritual energy of the Lord, we can make our
life successful...

I am so pleased to learn that you are lecturing in the Boston University
class in mysticism, and they are appreciating your versions. Please always
remain submissive in spirit to Krishna and the Spiritual Master, and by
their Grace you will get all strength to speak and satisfy your audience. I
remember when you were walking with me on the New York street, you were
proposing me to become lecturer in some University. And your honest desire
has been fulfilled by Krishna, that He has given sufficient strength unto
you, that instead of me, you are speaking there as my representative. This
is all Krishna's Grace. But one thing I may inform you, that the three books
which I have already prepared, namely, the Bhagavad-gita As It Is, Teachings
of Lord Caitanya, and Srimad-Bhagavatam, all these books are the ultimate
source of knowledge. If you simply reproduce what I have tried to explain in
those books, surely you will come out victorious, even in the midst of so
many great mundane scholars. The description given in these books, are not
mundane speculations, but they are authorized versions of liberated souls,
presented by our humble self. So the strength is not in us, but the strength
is in the Supreme Lord. And we have simply to present them without any
adulteration, in humble service spirit. That is the secret of success.

So far your center is concerned, you are trying your best, and Krishna
will help you. Go on doing like that, and our business is to try our best.
Results we leave for consideration of Krishna, and we shall not be
disappointed whether the result is favorable or unfavorable. Actually there
cannot be any unfavorable result, because we are serving Krishna. One person
may be or may not be inclined to accept Krishna Consciousness, but that
doesn't matter, but if we try our best to make one person Krishna Conscious,
then our duty is carried out nicely. That is recognized by Krishna. In spite
of our best efforts, if things do not come successful, then there is no
fault on our side. That should be the principle of our preaching, we shall
try our best to convince others in Krishna Consciousness, and Krishna will
be pleased, that is our gain. (Letters from Srila Prabhupada 9/27/68,
10/15/68)

How will I make them understand this message of Krsna consciousness? I am
very unfortunate, unqualified, and the most fallen. Therefore I am seeking
Your benediction so that I can convince them, for I am powerless to do so on
my own. Somehow or other, O Lord, You have brought me here to speak about
You. Now, my Lord, it is up to You to make me a success or failure as You
like. (Srila Prabhupada)
