I don't disagree with the general sense of what you say ... however can spirituality be about improving what we are already, making us "better" ? a "better" person" ?
Can awareness be "better" ? Are we a "person" at all ?
This is the place to post whatever questions you have related to the teachings of Eckhart Tolle. The rest of us will do whatever we can to help you achieve a better understanding
Be present, be pleasant.
