Existence doesn't exist without a perceiver. Existence means it comes and goes. Ever changing. Beingness (you) is changeless. Beingness does not arise and subside as a perceived object. Beingness perceives the appearance and disappearance of all objects. EXISTENCE ONLY APPEARS. It is not who you are. It is being perceived by you, the SELF. You cannot know the Self; you can only BE the Self.  All things within existence comes and goes while you remain. No object has any beingness on it's own. They appear momentarily within beingness. They appear momentarily within you. They do not exist without you - BEINGNESS.  The mind and body is also being perceived by you. They also come and go, while you remain. Existence and Beingness are not the same. We experience existence while beingness (who you are), perceives these experiences.  The changeless perceiver is the reflection of the eternal reality (birthless, deathless, imperceivable) inside the realm of impermanence (birth and death). Beingness is not a concept. It is beyond concepts. It is the perceiver of concepts. All experiences are empty void of any beingness. They only appear to exist on their own. Have you ever experienced anything without BEING present. They depend on you. You do not depend on them. Without you they cannot exist, but you exist without them. Existence is not beingness. Existence is being perceived by being.
