So the single most vital step on your journey towards enlightenment is this : learn to dis-identify from your mind. Every time you create a gap in the stream of mind, the light of your consciousness grows stronger. One day you may catch yourself smiling at the voice in your head, as you would smile at the antics of a child. This means that you no longer take the content of your mind all that seriously, as your sense of self does not depend on it.
Instead of “watching the thinker”, you can also create a gap in the mind stream simply by directing the focus of your attention into the Now. Just become intensely conscious of the present moment. This is a deeply satisfying thing to do. In this way, you draw consciousness away from mind activity and create a gap of no-mind in which you are highly alert and aware but not thinking. This is the essence of meditation.
In your everyday life, you can practice this by taking any routine activity that normally only a means to an end and giving it your fullest attention, so that is becomes an end in itself. For example, every time you walk up and down the stairs in your house or place of work, pay close attention to every step, every movement, even your breathing. Be totally present. Or when you wash your hands, pay attention to all the sense perceptions associated with the activity: the sound and feel of the water, the movement of your hands, the scent of the soap, and so on. Or when you get into your car, after you close the door, pause for a few seconds and observe the flow of your breath. Become aware of the silent but powerful sense of presence. There is one certain criterion by which you can measure your success in this practice : the degree of peace that you feel within.
