The Surangama Sutra chooses, as the best meditation method for the present historic cycle, the one used by Avalokitesvara. It disengages bodily hearing from outward sound, then penetrates still deeper into the void beyond this duality, then beyond ego and its object, until all opposites and dualities vanish, leaving absoluteness. Nirvana follows as a natural consequence. In other words, disengage consciousness from the senses and return to pure Consciousness itself.
