Guilt, regret, resentment, sadness & all forms of nonforgiveness are caused by too much past & not enough presence.
Eckhart TolleEgo means self-identification with thinking, to be trapped in thought, which means to have a mental image of "me" based on thought and emotions. So ego is there in the absence of a witnessing presence.
Eckhart TolleSome people say it is hard to live in such a way, being completely one with the present moment. Of course, it is not hard. The opposite is hard. Not being one with life is hard, and that is how most people live.
Eckhart TolleSo the single most vital step on your journey toward enlightenment is this: learn to disidentify from your mind. Every time you create a gap in the stream of mind, the light of your consciousness grows stronger. One day you may catch yourself smiling at the voice in your head, as you would smile at the antics of a child. This means that you no longer take the content of your mind all that seriously, as your sense of self does not depend on it.
Eckhart TolleThe power of the heart is to be connected with who you are at the deepest level. The power of the heart is the power of life itself, the power of the very intelligence that pervades and underlies the entire universe. It is a power that lies at the very heart of the universe. So to live in connectedness with that, then you are in touch with the power of the heart.
