A devotee named Amritanatha Yati wrote on a paper a
Malayalam verse imploring Bhagavan to say whether he was Hari (Vishnu) or Sivaguru (Subrahmanya) or Yativara (Siva) or Vararuchi. Bhagavan wrote his reply in the same Malayalam metre on the same paper. A translation of it is given below.
In the recesses of the lotus-shaped Hearts of all, beginning with Vishnu, there shines as pure intellect (Absolute Consciousness) the Paramatman, who is the same as Arunachala Ramana. When the mind melts with love of Him, and reaches the inmost recess of the Heart wherein He dwells as the beloved, the subtle eye of pure intellect opens and He reveals Himself as Pure Consciousness.
