This nothingness is not just the space that allows all matter to exist. It is also the complete silence that is the birthplace and graveyard of all sounds. It is the stillness that allows us to detect any and all motion. This nothingness allows reality to exist as a contrast to itself. But it remains part of everything that it enables to exist.
Focusing on nothingness helps to still the mind. This is because you must be in tune with the moment to be aware of nothingness. Being in tune gives birth to intuition and inspiration. Zen Buddhists (among other spiritual scriptures and teachings from around the world) often speak of nothingness in various sayings. Here are a few:
"We shape clay into a pot, but it is the emptiness inside that holds whatever we want." ~Tao Te Ching
"Knock on the sky and listen to the sound!" ~Zen saying
"What is the color of wind?" ~Zen koan
"The purpose of a fishtrap is to catch fish, and when the fish are caught, the trap is forgotten.So why all the riddles and talk of nothingness? It is because paradoxically, in nothing is everything. When you focus on true nothingness, you are focusing on an infinite amount of possibilities. A more vibrant depth and deeper understanding may be gained by examining what is not there.
The purpose of a rabbit snare is to catch rabbits. When the rabbits are caught, the snare is forgotten.
The purpose of words is to convey ideas. When the ideas are grasped, the words are forgotten.
Where can I find a man who has forgotten words? He is the one I would like to talk to." ~Chuang-Tsu
Focus on nothingness.
