That which rises and sinks is made up of what it rises from. The finality of the universe is the God Arunachala. Meditating on Him or on the seer, the Self, there is a mental vibration 'I' to which all are reduced. Tracing the source of 'I', the primal 'I-I' alone remains over, and it is inexpressible. The seat of Realisation 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. The only useful purpose of the present birth is to turn within and realise it. There is nothing else to do.
Ramana MaharshiSeeing God without seeing the Self, one sees only mental image. Only he who has seen Himself has seen God, since he has lost individuality, and now sees nothing but God.
Ramana MaharshiThe Self is the heart, self-luminous. Illumination arises from the heart and reaches the brain, which is the seat of the mind. The world is seen with the mind; so you see the world by the reflected light of the Self.
Ramana MaharshiGod illumines the mind and shines within it. One cannot know God by means of the mind. One can but turn the mind inwards and merge it in God.
