Even the structure of the atom has been found by the mind. Therefore the mind is subtler than the atom. That which is behind the mind, namely the individual soul, is subtler than the mind.
Ramana MaharshiPure Consciousness, which is the Heart, includes all, and nothing is outside or apart from it. That is the ultimate Truth.
Ramana MaharshiHe who has realized the Self in the Heart has transcended the dualities and is never perplexed.
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.
