“The mind will subside only by means of the enquiry ‘Who am I?’.  The thought ‘Who am I?’, destroying all other thoughts will itself be finally destroyed like the stick used to stoke the fire…..When the mind unceasingly investigates its own nature it transpires that there is no such thing as mind. The mind is merely thoughts. Of all the thoughts the thought ‘I’ is the root. Therefore the mind is only the thought ‘I’.  From where does the is ‘I’ arise? Seek for it within; it then vanishes.  This if the pursuit of wisdom.” p88
