Eckhart Tolle describes personal identity as a surface ripple on an ocean of universal consciousness. Your individual self is generated by something deeper and all-pervading, much like waves arise from the ocean itself. The true essence of who you are lies beyond the ego.

So the most important discovery for you is discover there's something deeper in you than the you, the person. They are not separate in the same way that the ripple on the surface of the ocean is not separate from the ocean. The ripple is a surface phenomenon. It's something that the ocean It does. And you are something that consciousness, universal, the one universal consciousness that pervades the entire universe, that is transcendent to this universe, it is something that consciousness does. It creates the image of a person like the ocean produces a ripple or a wave on the surface. Every human is a ripple on the surface of being, the vastness of being, of consciousness.
