Imagine that your mind is like a garden. You can simply be with it, looking at its weeds and flowers without judging or changing anything. Second, you can pull weeds by decreasing what's negative in your mind. Third, you can grow flowers by increasing the positive in your mind. In essence, you can manage your mind in three primary ways: let be, let go, let in.

In the light of an accepting, nonreactive awareness, your negative thoughts and feelings can sometimes melt away like morning mists on a sunny day.

Remember that this requires a conscious choice to make these efforts and you may have to go against your natural instincts at first.
