So far for humans it has been the case that ego develops and then humans are stuck with it for the rest of their lives.
Eckhart TolleFeeling will get you closer to the truth of who you are than thinking. I cannot tell you anything that deep within you don't already know. When you have reached a certain stage of inner connectedness, you recognize the truth when you hear it. If you haven't reached that stage yet, the practice of body awareness will bring about the deepening that is necessary.
Eckhart TolleFor some people, it's the beginning of an awakening when they hear or read, "You have a voice in your head that never stops talking. Have you noticed that?" And suddenly they become aware that the thoughts go through their heads, whereas before they were so identified with them that they were those thoughts.
