If you did not want your hand to move then it would have remained stationary.
If you did not want your hand to move then it would have remained stationary. Thus, your will becomes the unseen cause. The same would be with look at something. The looking is an action, which can be classified as an effect. You are the cause of it. If you did not initiate it, then the looking could not have been. You listen to what your teacher is saying. This listening is an action based on you. Your listening exists only because you do.
It is an effect of your existence - which is the cause in this case. From these examples, we can further see that the effect is based on and related to the cause. You look after your friend and take care of him. The caring that you show is related to your self. If you are not there, your kindness to him will not be there. Similarly, your knowledge is related to your existence. If you are not there, your knowledge and any actions resulting from it will also cease to be.
There is a special connection between your knowledge, your kindness, your Iraada (Willingness) and your self. All these qualities are related to and in need of you. This special relationship is called Eliyyat (Cause and Effect). Your actions are related to you and their existence is from your own existence. You are the one who moves, who writes, who walks, who talks, who thinks, who understands, who shows love, who knows and decides.
All these actions are effects and you are the cause of them all. Because of you, they exist. In his life, man will always consciously or subconsciously work with the knowledge he has of causes and their effects. When he finds himself thirsty, he looks for water to quench his thirst. When he feels the pangs of hunger, he eats. When he feels cold, he lights a fire.
He does all this because experience has taught him that water is the cause of removing thirst, food is the cause of appeasing hunger and fire is the cause of bringing warmth. Even in our daily lives, we react by searching for causes e.g. when we hear an noise, we look around for its source (cause) because we know that it could not exist without one; when we enter a dark room, we immediately search for the switch to turn on the lights.
Doctors study the causes of diseases in order to find cures to them. To explain to others what you have in mind, you have to speak. Cause and effect is a common sense that is part and parcel of our lives. Every human being is aware of this issue and he understands, accepts and he bases his life on it naturally.
