EVERYTHING is happening in YOU. The sounds, voices, pictures, images, sensations, feelings, emotions, thoughts, etc. Even these words… the voice you hear right now in the head is happening in YOU, not me! A bird’s chirp or a car’s horn… all appearing in YOU spontaneously.
There is nothing that is not you and yet, paradoxically, stunningly, nothing is you. You are both here and not here. To the mind, this makes no sense which is why trying to “figure this out” doesn’t work. It’s like using a can opener to explain water… both are 100% appearances, so neither can explain the other. We must go deeper… past all appearances to their silent source… and rest in/as that… where nothing is “known,” yet all emanates from.
