You have to ask yourself the question 'Who am I?' This investigation will lead in the end to the discovery of something within you which is behind the mind. Solve that great problem and you will solve all other problems.
Ramana MaharshiSee who is the subject; and this inquiry leads you to pure Consciousness beyond the subject.
Ramana MaharshiThere is no mind to control if you realise the self. The mind having vanished, the self shines forth. In the realised man, the mind may be active or inactive, the self remains for him.
Ramana MaharshiConcentration is not thinking of one thing. On the contrary, it is excluding all thoughts, since all thoughts obstruct the sense of one's true being. All efforts are to be directed simply to removing the veil of ignorance. Concentrating the mind solely on the Self will lead to happiness or bliss. Drawing in the thoughts, restraining them and preventing them from straying outwards is called detachment (vairagya). Fixing them in the Self is spiritual practice (sadhana). Concentrating on the heart is the same as concentrating on the Self. Heart is another name for Self.
Ramana MaharshiWhy should we... constantly worry ourselves... as to what should be done and how, and what should not be done and how not? We know that the train carries all loads, so after getting on it why should we carry our small luggage on our head to our discomfort, instead of putting it down in the train and feeling at ease?
