Meditation is sticking to one thought. That single thought keeps away other thoughts; distraction of mind is a sign of its weakness; by constant meditation it gains strength.
Ramana MaharshiGrace is within you. Grace is your self. Grace is not something to be acquired from others. If it is external, it is useless. All that is necessary is to know its existence is in you. You are never out of its operation.
Ramana MaharshiThat 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.
