Krishna can change anything, therefore we worship Him as the greatest Scientist. If a man knows swimming, he can stay up. So if a man has this much power, what to speak of God. So we see that Ramachandra has the art how to make stones float. It is a question of knowing the art. Art means the display of intellectual energy. Everywhere we can see intelligence in everything. So the lord knows the art of everything, so He can change anything, we cannot.
Letter to Rupanuga, May 03, 1972.
Srila Prabhupada has said about the power of Sri Krishna. Yes, Sri Krishna is quite powerful. He can change your fate if you pray in front of him with full devotion. It is your devotion that will promote you to a new spiritual conscious state. It will help you get the peace that you are searching here in this material world. The material world is not peaceful as everybody is chasing money, power and property. We need to be a good follower of Sri Krishna and this will help us become the perfect person to be a follower of Sri Krishna. Our life is full of obstacles but we can overcome these obstacles if we become a faithful follower of Sri Krishna. We can gain the spiritual intelligence through the study of the Bhagwad Gita. We must attend the classes also. The lectures from an enlightened spiritual master opens our consciousness. We understand what should we do in practical life to attain Krishna consciousness. In our life, we are changed by materialistic ideas and these ideas for money, property and power pulls us down. If we run after them, then we will never reach the goal of liberation. Our consciousness will be with those materialistic things only. We will lead a life, which far lower than the spiritual life. There are people in this world who go on chasing wealth in spite of having them. So we must stop chasing and lead a happy life at a certain point of time.
