the enemy within
That is one aspect of the answer Naomi received. I'm using her case only as a leaver to tease open multiple implications of the 'enemy'.
When that person said, "You are the enemy", indeed, that we are our own worst enemy is one highly relevant insight. Our minds are full of romantic words and aspirations, but when we can't turn those into life facts, then something inside, is a traitor. Alas, the truth is much less dramatic - the failure lies in the chain of command. It's because we failed to develop will, that's all, and that places us in the same boat as 99% of humanity... so no big deal - we are simply just like everyone else - a hypocrite.
But there is another aspect to interpreting that we, ourselves, are the enemy.
Recall Gurdjieff's comment, that the path to personal awakening is against God. In DJ's terminology, to awaken in will means to break the Eagle's command. Once you turn that inner switch, to actualization, everyone around you instinctively knows that you are their enemy.
In the early stages of the path, this is a serious turmoil. But as one progresses, it becomes a skill of the craft, to manage multiple layers. Nonetheless, the tension, and instinctive, subconscious dissonance between those surrounding us who remain within, and we who have dislocated from, the command, is always there, like a primaeval alligator whom we dance around. For how long?
The distinction between these two aspects is the 'awakening of will'. So long as we have failed in that task, everyone around accepts us, because we are within the command. Oh sure, they will compete and attack, but that's all within the command's parameters. It's all within the game. Once we succeed in awakening the will, then we sense the alligators eyes in the mud for the first time.
