The experience of vajra nature is more than perception; it is just what we have. Perception means that you perceive something, but here there is no separation between perception and perceiver. So the experience of vajra nature is not even an experience; it just happens. Vajra nature is nonconceptual and happens without perception, and without collecting further reference points or recording anything in the subconscious mind. Vajra nature just happens.
