Mind is consciousness which has put on limitations. You are originally unlimited and perfect. Later you take on limitations and become the mind.
Ramana MaharshiFrom 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 MaharshiBecause truth is exceedingly subtle and serene, the bliss of the Self can manifest only in a mind rendered subtle and steady by assiduous meditation.
