  • The Wind and the Moon (Friendship)

    Posted on February 20th, 2012 rudrarup No comments

    Once upon a time, there were two very good friends who lived together in the shade of a rock. Strange as it may seem, one was a lion and one was a tiger. They had met when they were too young to know the difference between lions and tigers. So they did not think their friendship was at all unusual. Besides, it was a peaceful part of the mountains, possibly due to the influence of a gentle forest monk who lived nearby. He was a hermit, one who lives far away from other people.

    For some unknown reason, one day the two friends got into a silly argument. The tiger said, “Everyone knows the cold comes when the moon wanes from full to new!” The lion said, “Where did you hear such nonsense? Everyone knows the cold comes when the moon waxes from new to full!”
    The argument got stronger and stronger. Neither could convince the other. They could not reach any conclusion to resolve the growing dispute. They even started calling each other names! Fearing for their friendship, they decided to go ask the learned forest monk, who would surely know about such thing.

    Visiting the peaceful hermit, the lion and tiger bowed respectfully and put their question to him. The friendly monk thought for a while and then gave his answer. “It can be cold in any phase of the moon, from new to full and back to new again. It is the wind that brings the cold, whether from west or north or east. Therefore, in a way, you are both right! And neither of you is defeated by the other. The most important thing is to live without conflict, to remain united. Unity is best by all means.”
    The lion and tiger thanked the wise hermit. They were happy to still be friends.

    The moral is:
    “Weather comes and weather goes, but friendship remains.”

  • Pinhole Camera

    How does a camera change a big scene into a small picture? To see for yourself, make a pinhole “camera.” Start with an empty cardboard box. Punch a hole in the center of the bottom by pushing a pencil through it.

    Now place a piece of waxed paper over the open end of the box and hold it there with tape or a rubber band. Your pinhole camera is complete.

    Sit in a dim room that has a bright object in it, such as a lamp or a window that lets in daylight. Lay a blanket over your head and the pinhole camera.

    Hold the camera at arm’s length, with the waxed paper toward you and the punched-out hole sticking out from under the blanket. Point the camera at the bright object. On the surface of the waxed paper, you will see a picture of the object—backward and upside down. Read the rest of this entry »
