Go deep into the sense of ‘I am’ and you will find. How do you find a thing you have mislaid or forgotten? You keep it in your mind until you recall it. The sense of being, of ‘I am’ is the first to emerge. Ask yourself whence it comes or just watch it quietly. When the mind stays in the ‘I am’, without moving, you enter a state, which cannot be verbalized, but which can be experienced. All you need to do is to try and try again. After all the sense of ‘I am’ is always with you, only you have attached all kinds of things to it- body, feelings, thoughts, ideas, possessions and so on. All these self-identifications are misleading, because of these you take yourself to be what you are not.
