Moving away from ego is an act of awakening, and it opens the door to so much more. However, we live in a physical world and therefore we are bound to get caught up in situations that trigger our ego.
In an interview about ‘gurus’, Mooji was asked whether he (as a guru) gets caught up in ego, and he answered, “Momentarily, all the different energies can play, sometimes sadness comes, sometimes anger comes, fear might come, but they cannot grow, they cannot linger because there is no soil for them to linger. They can only linger if you become personal with these things, then these forces bite in.”
Being physical, we cannot do away with our mind. But we can create stillness within ourselves, we can experience source in ourselves, and we can bring in the peace inside. If we do that, we can be aware when ego surfaces, and successfully root it out of our current experience. 
Most people who ruffle our feathers are those who have an over-identification with their ego, and must feel important or right to be validated; but at the same time, it is also our ego’s that allow the ruffling of those very feathers. It is only through this type of recognition and awakening that we can remove ourselves from our ego as much as possible. As human beings we will most likely always have a degree of identification of the ego. Proper analysis of these habits and patterns must be established so that we may nip them before they set off our inner egocentric negativity. The payout of this tactic is well worth it, lifting huge burdens of emotional turmoil before they even begin; leaving you with time and energy to focus on the things in life that make you happy.
