Once upon a time. A man was sitting on the bank of a river and observing nature. At that moment he was becoming thrilled by seeing various activities of nature.Birds were chirping on the trees, the water streams in the river were jumping and flowing over the rocks, various beautiful butterflies were hovering over the flowers.He was becoming fascinated by her.He was filled with awe after seeing the arts. Curiosity about nature started increasing in his mind, filling it with many questions.Now he was not satisfied with just observing nature. He wanted to know the answers to the questions that arose in his mind. But who should he ask about nature? If someone else responded, he would describe the image of nature as seen by that person himself.Therefore, there had no option to ask those questions to any other person. It is like asking a tree, what is the secret of its green leaves?
