Ego ultimately is the expansion of self, which means primarily, when you love someone – the Herbrew word love, has in it, the word to give – when you love someone you seek to give to them. So ironically, the person who loves themselves seeks the expansion of themselves, but this is very important – for the same applies to if you love someone else, which is why the ultimate is to Not have any illusions of grandeur. In fact, humility and at the same time, your love for G-d should be such that this is what you wish to expand.
