If anatta is a reality, then how do you explain Volition or Will? I'm just trying to understand the concept of anatta better here. Buddhism tells me there is the concept of no-self (anatta), and even the so called conditional self is actually an illusion that arises out of my ignorance (correct me if I'm wrong).

But psychology tells me on the other hand, that there exists something called Volition or Will. From Wikipedia:


  Volition or will is the cognitive process by which an individual decides on and commits to a particular course of action.


So you see, there needs to be an individual or self who needs to take the decision or make the will, so to speak. As a practical example, I decide to lift my hand right now, and lo and behold! my hand is lifted instantly. So, who is this decision-maker or will-maker that made the decision of lifting the hand? You say there is no self?

Now saying that the conditional self made the decision is not something I'm going to buy. How can anything as lowly as an illusion, decides to take control of things and make an impact on the real world? It is just an illusion after all. That's the reason I'm unable to bring anatta in sync with this practicality of life, however hard I try. Please care explain how do you explain volition if anatta is a reality?
Anatta means that there is no permanent self, not that there is no self at all. That would be just silly and contradict observation. Imagine the self as a car. Every day one part of the car is replaced with another. One day the right headlight, the other day the windscreen, the third day the rear left wheel. And so on. At some point, all the pieces of the car have changed, but can you say exactly when the first car changed into the second? You can't, but at the same time you can't claim that the car you end with is the same as the car you began with. Similarly, just think about yourself when you were five years old. Was it you, was it another version of you, or was it another person, with different tastes, making different choices?

The key point is that self and will are conditioned phenomena subject to change, to birth, to death. So the decision-maker and the will-maker are conditioned, constructed phenomena subject to change, birth, death. There is some uncanny science going on that shows that sometimes we make decisions before we are aware of having made them. Who is the will-maker now? The real illusion is not that there is a conditional self or not, but that we are in power.
