That which is real must be real for ever.

Ramana Maharishi:  You create a dream body for yourself in the dream and act with that dream-body. The same is falsified in the waking state. At present you think that youare this body and not the dream-body. In your dream this body is falsified by the dream-body. So that, you see, neither of these bodies is real. Because each of them is true for a time and false at other times. That which is real must be real for ever. But you say ‘I’. This ‘I’-consciousness is present all through the three states. There is no change in it. That is alone real. The three states are false. They are only for the mind. It is the mind which obstructs your vision of your true nature. Your true nature is that of infinite spirit. That was the case in your sleep. You note the limitations in the other two states. What is the difference due to? There was no mind in sleep, but it exists in the dream and the waking states. The feeling of limitation is the work of the mind. What is mind? Find it. If you search for it, it will vanish by itself. For it has no real existence. It is comprised of thoughts. It disappears with the cessation of thoughts.
