That is the ego which rises and sinks periodically. But you exist always. That which lies beyond the ego is consciousness - the Self.
Ramana MaharshiOnce the current of awareness of the self is set afoot, it becomes everlasting and continuous by intensification.
Ramana MaharshiMeditation 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 MaharshiSpeaking of Self-realizatio n is a delusion. It is only because people have been under the delusion that the non-Self is the Self and the unreal the Real that they have to be weaned out of it by the other delusion called Self-realizatio n; because actually the Self always is the Self and there is no such thing as realizing it.
