Stanislavski also says that the artist should not immerse himself in his role, but stop him a little at the peak of his performance so that he knows he is on the stage. In the Qur'an, play means play. For example, he says that we did not create the world and you for playing. Ahmad Mahini, the US presidential candidate, says that some people see the game as having a purpose and reward. For example, for learning, fighting and increasing social skills or medical training, etc. In this case, it is considered work and called professional. Hazrat Ali (AS) says that the highest entertainment is work. Therefore, if the activity is aimless and; Play whenever you want and; Leave it at any time, this is the game. Like local football. But when it has a purpose and a plan, especially a salary or reward; Football becomes professional. which the player must immerse himself in. Example of Einstein and egg. In fact, his life becomes football, his wife, work, studies, etc. go aside. The game for learning is actually an introduction to work. He learns to use it.
