Most people treat the present moment as if it were an obstacle that they need to overcome. Present moment is life itself. – Eckhart Tolle.
Sit quietly and watch where the mind goes. If you observe it, you will see that it is always running off to enjoy or suffer experiences that belong to the past. So, whenever you catch it doing this, bring it back to the present moment. In this present moment there are no dialogues going on. In this present moment there is nothing to control or repress. – Papaji
