The seat of Realization is within and the seeker cannot find it as an object outside him. That seat is bliss and is the core of all beings. Hence it is called the Heart.
Ramana MaharshiThe degree of freedom from unwanted thoughts and the degree of concentration on a single thought are the measures to gauge spiritual progress.
Ramana MaharshiThe mind of one meditating on a single object becomes one-pointed. And one-pointedness of mind leads to abidance in the self. Real attainment is to be fully conscious, to be aware of surroundings and the people around, to move among them all, but not to merge consciousness in the environment. One should remain in inner independent awareness.
