A scientific understanding of Reiki must provide some form of explanation for this ancient perspective. Until very recently, there was no scientific framework from which to view the Eastern philosophy that underlies Reiki Energy Healing. But now, thanks to recent advances within the sciences allowing Westerners to think outside the box of concrete Newtonian Theory, progressive sciences like String Theory, Unified-Field Theory, and Quantum Physics are lending validity to the energy-based medicines and healing modalities.
In history, people worshiped the sun and associated its absence with the end of the world thus, they greatly feared eclipses. Devoid of scientific knowledge, they thought that the eclipse signifies the death of the sun and ultimately, the death of all. For one, the ancient Egyptians worshiped a sun god that they call Ra. Images of this sun god has been seen in various Egyptian artifacts and was a big part of the religion in ancient Egypt.
Death has always been a thought-provoking mystery for all of us. A common belief is that it is the end of our human lives and that when our bodies die, we die with it too. And the greatest calamity that has happened to the human mind is that he is against death. Being against death means you will miss the greatest mystery. People are not afraid of death, they are afraid of losing their separation, they are afraid of losing their ego and personality.
