The whole universe is only mental. (p. 351)

The srutis and the sages say that the objects are only mental creations. They have no substantive being. Investigate the matter and ascertain the truth of this statement. The result will be the conclusion that the objective world is in the subjective consciousness. The Self is thus the only Reality that permeates and also envelops the world. Since there is no duality, no thoughts will arise to disturb your peace. This is Realization of the Self. (p. 382)

You are That, here and now. (p. 77)

The Self is the only Reality. (p. 38)

The universe is only expanded Self. It is not different from the Self. (p. 77)

If you understand your own reality, then that of the rishis and Masters will be clear to you. There is only one Master and that is the Self […] The power is only one in all. (p. 110-111)

The Master is the same as God and not different from him. (p. 27)

Questioner: Can one read others minds? Ramana Maharshi: Where are others apart from one‘s own Self?

I Am is the name of God. Of all the definitions of God, none is indeed so well put as the Biblical statement "I Am that I Am" in Exodus (chap. 3). There are other statements, such as Brahmaivaham, Aham Brahmasmi, and Soham. But none is so direct as the name Jehovah = I Am. The Absolute Being is what is – it is the Self. It is God. Knowing the Self, God is known. In fact, God is none other than the Self. (p. 76)
