Yes, the world's heating up. There is too much movement and too much friction. Hence, the world is heating up. It may just errupt one day like the volcanic lava.
Movement of wheels and movement of feet. Movement of the brain, movement of the soul. If the movement happened in the same direction, there was a lesser possibility of conflict, or what I call friction. Unfortunately or fortunately(since I don't think being judgemental is very correct at this point in time), we all decide to move in various directions, all the time colliding, bumping on to each other. We talk, we converse, we argue. The kinetics have just scattered themselves. We have produced tremenedous amount of thermal energy.
We need rain.
