There are whole lot of missing links in the results of classical science investigations. Like how do you explain the dark matter in the universe with Newtonian Physics or how do you explain the asymmetry of matter and antimatter in the visible universe?
But there is no such unexplained phenomenon in Occult Science. It explains the connection between science, mysticism and spirituality quite successfully. And I found this book “The Snake And The Rope” quite successful in explaining the Occult Science.
If you want more information about these 3 then I think you should read this book and there is few free chapters available online: http://www.snakeandtherope.com
