What is the true purpose of EGO? And is it a hidden navigation system within us?

I recently had a download that the Ego wasn't meant to be a negative thing within our system. That is was actually meant to be a neutral component that we could use as a tool for navigating within our own systems. Kind of like the Queen in chess. Can move in all directions, has access to every part of every body we possess. (Physical, mental, emotional, etc....), and can travel between all planes of existence, within our own created realities that is. I mean it even contains the word "GO" in it.  I'm curious if our ego doesn't actually hold the key to everything we seek? Why wouldn't you hide the key to your every success, inside the one place nobody would think to look? I mean, we've been told it's a bad thing, and we should remove it. But I don't ever do as I'm told....lol So I humbly ask......What REALLY, is Ego? Was hoping the GFL could elaborate more on this very unique and powerful aspect of us. And again, thank you Elizabeth, for all the time and energy you have put, and continue to put into helping others. You've truly embraced the meaning of friendship and what it means to be of service to others:)
