Dear @chbartist sir!
History is a witness that the existence of anyone who has ego has merged into the soil. The way in which a negative and positive thought stream is good and evil, in the same way ego is also of two types which are reflected ( Negative) and the one who competes with himself (positive). In other words, one can say that one is related to your intellect, and by the second emotions.The other aspect of the mind can be kept in the category of ego. Protecting a strong ego makes sense. If you are emotionally connected to someone, then do not place the ego in there, otherwise everything will end.Ego builds a strong wall around us, so that we keep imprisoned. Use the ego as a shield, that is, use it to compete with yourself.
