Ramana Maharshi awakened at the age of sixteen through a spontaneous experience of death-recognition that left him certain of the deathless awareness underlying personal experience. He left home, travelled to the sacred mountain Arunachala in Tamil Nadu, and remained there for the next fifty-four years.
His teaching reduced to one question: Who am I? Not as an intellectual puzzle but as a practical investigation. To whom does the thought arise? Trace the I-thought back to its source. What is found is not another thought but the awareness in which all thoughts appear.
