ego perceives itself as a separate fragment in a hostile universe, with no real inner connection to any other being, surrounded by other egos which it either sees as a potential threat or which it will attempt to use for its own ends. The basic ego patterns are designed to combat its own deep-seated fear and sense of lack. They are resistance, control, power, greed, defense, attack. Some of the ego's strategies are extremely clever, yet they never truly solve any of its problems, simply because the ego itself is the problem.
— Eckhart Tolle
