To strengthen a thinker in itself is to strengthen the ego.
Because the thinker is the ego. -- Ramana Maharshi
But; you are not the thinker. -- Eckhart Tolle
You are the awareness behind the thought -- Eckhart Tolle
Because; Only that which is always with you can be said to be your self and if you look closely and simply at experience only awareness is always with you. -- Rupert Spira
