Mind means past. Mind has no idea of the present, cannot have any idea of the present. Mind only means that which has been lived, known, experienced -- the accumulated past.
It cannot have any contact with the present; it will have that contact only when the present is no more present and has become past. And life moves ahead. We live in the present and we move in the future, and mind never lives in the present and always clings to the past. This is the dichotomy, the greatest calamity. This is the knot that has to be cut.
