Its said that what is use of reading or learning the things which we can't understand because these things are of no use for us as we will not be able to use them without understanding them but the reality is not the same. In India a Hindi saying goes like "Rasari aavat javat sil par hot nishan" meaning the continuously on going and out coming rope is certain to leave marks even on the stones. Have you ever thought it is possible to create mark on stones? but this is the reality and need not any proof. The rope we use to dig the water from well, leaves its marks on the stones with time. The same thing happens with us, when we read any of our religious holly book or book of knowledge, though at the time of reading we might not understand it or even unable to say a single word about it as soon as we close it. My view point will be supported and illustrated with the following short story.
An old Farmer lived on a farm in the mountains with his young grandson. Each morning Grandpa was up early sitting at the kitchen table reading his Bhagavad Geeta. His grandson wanted to be just like him and tried to imitate him in every way he could. One day the grandson asked, "Grandpa! I try to read the Bhagavad Geeta just like you but I don't understand it, and what I do understand I forget as soon as I close the book. What good does reading the Bhagavad Geeta do?"
The Grandfather quietly turned from putting coal in the stove and replied, "Take this coal basket down to the river and bring me back a basket of water."
The boy did as he was told, but all the water leaked out before he got back to the house. The grandfather laughed and said, "You'll have to move a little faster next time” and sent him back to the river with the basket to try again. This time the boy ran faster, but again the basket was empty before he returned home. Out of breath, he told his grandfather that it was impossible to carry water in a basket, and he went to get a bucket instead.
The old man said, "I don't want a bucket of water; I want a basket of water. You're just not trying hard enough," and he went out the door to watch the boy try again.
At this point, the boy knew it was impossible, but he wanted to show his grandfather that even if he ran as fast as he could, the water would leak out before he got back to the house. The boy again dipped the basket into river and ran hard, but when he reached his grandfather the basket was again empty. Out of breath, he said, “See Grandpa, it's useless!"
"So you think it is useless?" The old man said, "Look at the basket."
The boy looked at the basket and for the first time realized that the basket was different. It had been transformed from a dirty old coal basket and was now clean, inside and out.
"Son, that's what happens when you read the Bhagavad Geeta. You might not understand or remember everything, but when you read it, you will be changed, inside and out. That is the work of Lord Krishna in our lives."
