A man was sitting by a lake. He was throwing small pebbles into it from time to time. A young boy happened to cross by. He was intrigued to see that after every few minutes or so, the man would toss a pebble into the lake. The boy went up to the man and said, "Good pastime, this stone throwing, he?" "Hmmm," said the man. He seemed to be deep in thought and obviously did not wish to be disturbed. Sometime later, the man said softly, "Look at the water, it is absolutely still." The boy said, "Yeah, it is." The man tossed a pebble into the water and continued, "Only till I toss a pebble into it now do you see the ripples?" "Yeah," said the boy, "they spread further and further."
The wise man said, "It is not possible to stop the movement of the water once a pebble has been thrown into it. But if we can stop ourselves from throwing the pebble in the first place, the ripples can be avoided altogether! So too, it is with our minds. If a thought enters into it, it creates ripples.”
The thought that develops within is critical in the life of any being. Thought-word-action is the formula of creation – everything begins from a thought. The episode mentioned above carries a great moral, but the task of blocking a thought from entering the mind is a risky affair. Any thought is energy and energy can neither be created nor be destroyed. So, it is reasonable to think that all thought waves beginning from the original Fundamental Vibration still exist in this universe and we are living in a dense pool of thought vibrations. In a prayer hall if spiritual thoughts are more intense, in a liquor bar it could be vibrations of sensual pleasures that dominate. This is why it is said that it is very important to generate and maintain positive vibrations in and around. It will not only protect you and your group but also saves all those who pass by.
