All thoughts are from the unreal ‘I’. i.e., the ‘I’- thought.

Devotee was asked to say what exactly was his method of meditation. He said: “Aham Brahmasmi” (“I am Brahman”).

Ramana Maharishi:  “I am Brahman” is only a thought. Who says it? Brahman itself does not say so. What need is there for it to say it? Nor can the real ‘I’ say so. For ‘I’ always abides as Brahman. To be saying it is only a thought. Whose thought is it? All thoughts are from the unreal ‘I’. i.e., the ‘I’- thought. Remain without thinking. So long as there is thought there will be fear.
