This instrumental is about the 26,000 year cycle the Earth/Humans go through, 13,000 years of light and then 13,000 years of dark. We are currently at the end of the dark cycle. Which is also known as "the end times" and "Kali Yuga". It's not the end of the world, just the end of the cycle, which is why the Earth is not a nice place to live right now, but cheer up, the golden/light age is coming up soon. Just hang in there.
