Don’t fill the emptiness with something. Wait for the emptiness to fill itself. Watch it filling itself. Watch it draining itself. Don’t manipulate it. Any manipulation fills nothingness with memories of what has been to predict the future.
Everything in your life has to originate from within yourself. Originate comes from original, unique, creative, new, unusual. Nothingness when allowed to fill itself will produce something that has never been.
I sit with nothingness, cycle through it, and by that I mean I don't run from unpleasant feelings until something materializes into the physical and then let it go.
