Even though both the mind and the world rise and set together, the mind lights the world. The source from which the mind and world rise and into which they set is the reality ( self or ataman ) that doesn’t rise or subside: Maharishi Ramana.
Comments:
Our self, which is an observer of our body and mind, is reality. Our mind is in front of us. We can see our minds, and we say, please tell me again, my mind, not hearing it was thinking of another person. So you can see your mind because it is different from the you(self ). When the mind goes out, we can see the world, and when it is inward, then the world disappears. In a deep sleep, there is no mind and, therefore, no world. In deep meditation or samadhi, there is no mind and world also. Only bliss shines here.
