Nothing and something is like black and white. Like a magnet with opposite poles. You have to have nothing to have something. If all you have was something how would you know it was something unless you had nothing to compare it to.

You see. Everything is a pulse. Black/white, something/nothing, loud/silent, hard/soft, etc. But between those is a whole range of spectrum. Between light and dark, is a whole range of color. The space in which matter exists is as important as the form itself. If there was no space would you know what form was?

Nothingness is the ultimate reality. From which something can manifest.
