The mind, to ensure that it remains in control, seeks continuously to cover up the present moment with past and future, and so, as the vitality and infinite creative potential of Being, which is inseparable from the Now, becomes covered up by time, your true nature becomes obscured by the mind. An increasingly heavy burden of time has been accumulating in the human mind. All individuals are suffering under this burden, but they also keep adding to it every moment whenever they ignore or deny that precious moment or reduce it to a means of getting to some future moment, which only exists in the mind, never in actuality.
— Eckhart Tolle
