What exists in truth is the Self alone. The world, the individual soul and God are appearances in it. Like silver in mother-of-pearl, these three appear at the same time and disappear at the same time. The Self is that where there is absolutely no 'I thought'. That is called 'Stillness'. The Self itself is the world; the Self itself is 'I'; the Self itself is God; all is Siva, the Self.
Ramana MaharshiEven 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 MaharshiPeace is for the purification of one's mind. Power is for the growth of the community. Having established the community with power, one should then establish supreme peace.
