The ego is not a thing but a subtle effort, and you cannot use effort to get rid of effort - you end up with two efforts instead of one. The ego itself is a perfect manifestation of the Divine, and it is best handled by resting in Freedom, not by trying to get rid of it, which simply increases the effort of the ego itself
