Why does the mind habitually deny or resist the Now? Because it cannot function and remain in control without time, which is past and future, so it perceives the timeless Now as threatening. Time and mind are in fact inseparable.
Eckhart TolleA true spiritual teacher does not have anything to teach in the conventional sense of the word, does not have anything to give or add to you, such as new information, beliefs, or rules of conduct. The only function of such a teacher is to help you remove that which separates you from the truth of who you already are and what you already know in the depth of your being
Eckhart Tolle
