He who knows the receptacle (Ayatana) verily becomes the receptacle of his people. Mind is verily the receptacle (of all our knowledge). (Chhandogya Upanishad, V-i-5)

That which separates you from God is mind. The wall that stands between you and God is mind. Pull the wall down through Om-Chintana or devotion and you will come face to face with God.
