Invisible subtle energy occurs around us all the time, and is measurable by science. Energy can be created and manipulated in many ways. It is the live blood of a civilization, and therefor an important resource.
As long as we think we are more advanced than we ever been, we are blind to technology based on subtle energies. Fate, destiny, karma, miracles, they're all intangibles in the invisible energies of the universe, yet their narratives, stories and conclusions are as visible as the ways they've been written, lived and ultimately shaped our life.
