Eckhart Tolle writes about the ego in his book A New Earth.

Eckhart Tolle says, "The extent of the ego's inability to recognize itself and see what it is doing is staggering and unbelievable. [...] To become free of the ego is not really a big job but a very small one. All you need to do is be aware of your thoughts and emotions – as they happen. This is not really a 'doing' but an alert 'seeing'. In that sense, it is true that there is nothing you can do to become free of the ego. When that shift happens, which is the shift from thinking to awareness, an intelligence far greater than the ego's cleverness begins to operate in your life. Emotions and even thoughts become depersonalized through awareness. Their impersonal nature is recognized. There is no longer a self in them. They are just human emotions, human thoughts. Your entire personal history, which is ultimately no more than a story, a bundle of thoughts and emotions, becomes of secondary importance and no longer occupies the forefront of your consciousness. It no longer forms the basis for your sense of identity. You are the light of Presence, the awareness that is prior to and deeper than any thoughts and emotions."
