Creation has no face value, the creation is continuous like a flow. Creation happens everytime. The past, present and future all the time-realities are happening simultaneously, and we are just shifting from one reality to another reality all the time just like the flow on a continuous basis.
Who is creating those realities?
The Mind is creating those realities, we all are connected to one mind. We are creating by the pictures of mind, and the pictures of one mind get connected to each other to form a creation.
