From where does this "I" arise? Seek for it within; it then vanishes. This is the pursuit of wisdom. When the mind unceasingly investigates its own nature, it transpires that there is no such thing as mind. This is the direct path for all. The mind is merely thoughts. Of all thoughts the thought "I" is the root.
Ramana MaharshiGod illumines the mind and shines within it. One cannot know God by means of the mind. One can but turn the mind inwards and merge it in God.
