See who is the doubter, who is the thinker. It is the ego. Hold it; the other thoughts will die away - the ego will be left pure. See the source from where the ego arises and abide in it. That is pure consciousness.

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.
Ramana MaharshiYou have to ask yourself the question 'Who am I?' This investigation will lead in the end to the discovery of something within you which is behind the mind. Solve that great problem and you will solve all other problems.
