There is a Sufi song:
A lover knocked at the door of his beloved. A voice cried, “Who is there?” The person outside said, “It is I.” He heard in reply, “This house has no place for two, ‘I’ and ‘Thou’.”
The closed door remained closed. The lover retreated into a forest. There he made penance, observed fasts, and offered prayers. After many years, he returned and again knocked on the closed door. Again the voice asked, “Who is there?”
This time the doors were thrown open, for his reply was, “It is thou.”
This reply, “It is thou”, is the essence of all religion. On the endlessly flowing river of life, “I” is the only bubble. “I” alienates the individual from existence. The bubble of “I” thinks itself distinct from the river, whereas in reality the bubble has no separate existence. It has no separate center, no separate life. It is the ocean. The ocean is its life. Its very existence is in and through the ocean. Even the idea of its being separate from the ocean is ignorance. Look into the bubble, and you find the ocean. Look into the ‘I’, and you find Brahman.
Where ‘I’ does not exist, ‘Thou’ too is absent. There is only ‘being’. Only existence, pure is-ness is there. To awaken into this pure existence is nirvana.
