If anyone were to explain or define silence as absence of sound, I'd say I've got news for you. Silence is a powerful dynamic with the power to change your life and alter your motives - that is, if you play its game.
Silence is as essential as air or water for our well-being, even survival as a species.
I've been catapulted into the awareness of silence, essential silence, so I know through personal experience. I also know by reading about other people's experiences and by comparing notes with those who have come into the same knowledge. And sadly, I am beginning to think that we may be about to lose track of one of our most powerful renewable sources of energy, a transformatory power available to all who care to make a go for it. Unless, of course, we try the experience and make it known worldwide. After all, it is not a new discovery, it is as old as mankind and lies at the heart of all great civilisations, until they begin to neglect it.
