The self within every human being is three selves that control his thoughts and feelings
Within every human being are three selves:
1- The animal self Id
It is unconscious, driven by instincts, and does not know values, laws or religions. All you want is to enjoy without conditions or restrictions, as if the motives that drive it are primarily animal.
2- The human self (ego) Ego
She is emotional and conscious, but she relies on cunning, hypocrisy and evasion, but she is afraid because she avoids harassment for fear of being exposed or despised by society, custom, religion, or people's reaction.
3- The ideal self or superego
This self stands as a dividing line between the feeling and the unconscious, and it monitors the human self (the ego), but its problem is very weak, so it is overcome by the explosions of the animal self due to repression; This self is called "the conscience".

Imagine that you (the ego) and you have a demon (the animal self) and an angel (the ideal self) helping to control and not control your thoughts and actions..!
