Walking in the dense fog has something strange. Sounds are dim, cold creeps up your spine and vision is limited to the close proximity. This way of perception is like looking to the world from within a bubble. Only the colours are missing. But colours can be made up by the mind as an undetachable part of perception. The mind makes it up for its own.
Experiences add new colours. The mind creates its own puzzle. Your colours are not mine. That is why the tones of grey are neutral. This way of looking to the world wipes the restlessness away. Silence and limited vision allow focusing on the things close to you. Can it bring your Troubled mind to rest ?
