I [Yogi Ramaiah] asked [Ramana] Maharshi about contemplation. He taught me as follows: When a man dies the funeral pyre is prepared and the body is laid flat on the pyre. The pyre is lit. The skin is burnt, then the flesh and then the bones until the whole body falls to ashes. What remains thereafter? The mind. The question arises, ‘How many are there in this body – one or two?’ If two, why do people say ‘I’ and not ‘we’? There is therefore only one. Whence is it born? What is its nature (swaroopa)? Enquiring thus the mind also disappears. Then what remains over is seen to be ‘I’. The next question is ‘Who am I?’ The Self alone. This is contemplation. It is how I did it. By this process attachment to the body (dehavasana) is destroyed. The ego vanishes. Self alone shines.
