I am only reminding you
An existence is claimed only after observation.
Existence is state of presence in observation.
The mind changes the concept by applying “existence” to the object, forgetting that the “existence” derived from (and actually is) awareness about presence.
Awareness is needed in order to make the existence valid.
We work with “existence” more like a meaning (concept), but after it was created by the awareness the mind deceivingly is applying it to the object.
Actually the existence is applicable to the awareness.
We wouldn’t talk about existence if we never observed it.
If we only have self-awareness without any other knowledge, existence is impossible as a concept (meaning, knowledge).
Because any existence is observed through our five senses we can say that all things are already known to us through the concepts created in the observation.
