The degree of freedom from unwanted thoughts and the degree of concentration on a single thought are the measures to gauge spiritual progress.
Ramana MaharshiYou 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 MaharshiIf the ego rises, all else will also rise; if it subsides, all else will also subside.
Ramana Maharshi
