Looking at the same event through an angle other than that...
Looking at the same event through an angle other than that of visual appreciation, we can see that when we see leaves moving we immediately register that this movement is a result of the wind blowing against them. Therefore, it would be correct to say that the wind is the Cause of the stirring of the leaves i.e. if the wind did not blow, then it would not Result in the leaves moving.
Thus, we can call the actual movement of the leaves - Ma'lool (Effect) and the wind itself - Ellat (Cause) Let us look at another example that has been made famous in scientific history. We all know the story of the famous philosopher/scientist who sat under an apple tree. As he pondered, one apple suddenly dropped to the ground.
He picked it up, looked at it, smelt it and then wondered to himself 'Why did the apple fall down?' From this simple and obvious question, the man went on to discover the force of gravity, which is today one of the most important aspects of physical science. Here we can say that the falling down of the apple was the Ma'lool and the gravity of the earth was the Ellat. Let us look at a third example to make things even clearer. Imagine that you have sat down in a room with your back to a wall.
Strangely, as you lean back, you feel heat emanating from the wall and wonder to yourself what the cause of the heat can be. Seeking your answer, you leave the room and try to search for what is on the other side of that particular wall. When you reach there, you see a heater attached to it and everything falls into place! Now you understand what the cause of the heat is and the hot wall is no longer a mystery. In such a case, the heater is the Cause and the warm wall is the Effect.
If there had not been a heater then the wall would not have been warm. All this shows us that cause and effect are two halves of a complete relationship. Without a particular cause, its effect would no longer exist. Therefore we can conclude that in our world full of existence, there is an underlying system based on the theory of cause and effect. The Non-Physical State Cause and effect do not always manifest themselves in the visual or physical world as in the examples above.
Sometimes we can see only the cause and sense the effect, at others it may be the opposite i.e. we sense the cause and see the effect. For example, move your hand. This movement of the hand is the effect of your willing the action to happen.
