ur own pain

Because your ego is strong, and you are so unaware of its power, any thought or idea that differs from yours upsets you and you take it personally when it wasn't personal idea at all, ideas, thoughts, concepts are not you, especially when most of what you think doesn't come from you, but is just a product of your experiences and what people have told you, most of which you know is a lie,most of which you believe is a lie, but you are not aware of it, so you defend it and all, as though it is a representation of who you are and how you are and what you think, this is the basis of all anger, your own ego, anger can not exist without ego, and your happiness can not bloom when your ego is in control
