Q – What is liberation ( Mukti) ?
Therefore, leaving the corpse-like body as an actual corpse and remaining without even uttering the word ‘I’ by mouth, if one now keenly enquires, ‘What is it that rises as ‘I’? then in the Heart a certain soundless sphurana, ‘I-I’, will shine forth of its own accord. It is an awareness that is single and undivided, the thoughts which are many and divided having disappeared. If one remains still without leaving it, even the sphurana – having completely annihilated the sense of the individuality, the form of the ego, ‘I am the body’ — will itself in the end subside, just like the flame that catches the camphor. This alone is said to be liberation by great ones and scriptures. – Shri Ramana Maharshi
