Space is not empty. It is full, a plenum as opposed to a vacuum, and is the ground for the existence of everything, including ourselves. The universe is not separate from this cosmic sea of energy.
David BohmDialogue is really aimed at going into the whole thought process and changing the way the thought process occurs collectively. We haven't really paid much attention to thought as a process. We have engaged in thoughts, put we have only paid attention to the content, not to the process. Why does thought require attention? Everything requires attention, really. If we ran machines without paying attention to them, they would break down. Our thought, too, is a process, and it requires attention, otherwise its going to go wrong.
