The Principle of Universal Connection and Development

You are not alone. We are all connected as one universally by aether and we're all part of everything that happening right here and now. Referred to as 'akasha' in Sanskrit, aether is the element that is without the firmness of earth, the coolness of water, the heat of fire or even the movement of wind. It is therefore the very essence of 'emptiness'. The space element is the most subtle of all elements.
