@Arman rightly points out that this is because of lack of of education,

Of course, ego is just an idea. Ego here means the identity of the Self. What normally identified as Self is ego. For example, I am writing this post. This I-ness is ego. This ego is false and it should be overcome. How? Of course, by identifying the true-self. How could you identify it. By self-enquiry. Who am I? Am I this body? Am I this mind? Am I anything beyond this? A sincere meditation upon the questions like these will lead you to Self-Actualisation.
