Have you observed what is happening in your mind every moment? It vacillates between the past and the future. It is either in the past, occupied with what has happened, or in the future thinking about what you have to do. There is another tendency of the mind—it clings onto the negative. If 10 positive events are followed by one negative event, the mind will cling to the negative. It will simply forget the 10 positive events. With meditation however, you can become aware of these two tendencies of the mind and bring it to the present. Happiness, joy, enthusiasm, efficiency and effectiveness are all in the present. When you culture your mind with meditation, its tendency of holding on to negative emotions simply disappears. You gain the ability to start living in the present moment and are able to let go of the past.
