The question of light; its source and its purpose has interested man through the yugas. Because the night sky in every age is omnipresent, mankind has applied its mind to figuring out how the sun, moon and stars affect our wellbeing. Eventually scientists could measure the speed of light. Now we can understand that the physical world is only the smallest part of Light’s domain. The emanation of spiritual light gives us a meaningful understanding of this topic: the redeeming light.
