Maybe part of the beauty of life is knowing that we can never know the fullness of the ground of Being. The ability to search and learn and to continue growing is what makes it most interesting.
Then there are those who say it is just the imagination. Such a wonderful thing to see what we imagine the world to be and the 'beyond'.
If we take care of our current state or stage, the rest will unfold as its meant to be. This is the only moment where we seem to have any control. So let us continue to love, to learn, and to grow.
