If the man feels himself to be the screen on which the subject and object are projected there can be no confusion

Devotee:  What is sphurana (a kind of indescribable but palpable sensation in the heart centre)?

Ramana Maharishi:  Sphurana is felt on several occasions, such as in fear, excitement, etc. Although it is always and all over, yet it is felt at a particular center and on particular occasions. It is also associated with antecedent causes and confounded with the body. Whereas, it is all alone and pure; it is the Self. If the mind be fixed on the sphurana and one senses it continuously and automatically it is realisation. Again sphurana is the foretaste of Realisation. It is pure. The subject and object proceed from it. If the man mistakes himself for the subject, objects must necessarily appear different from him. They are periodically withdrawn and projected, creating the world and the subject’s enjoyment of the same. If, on the other hand, the man feels himself to be the screen on which the subject and object are projected there can be no confusion, and he can remain watching their appearance and disappearance without any perturbation to the Self.
