Spirituality is a product of the spiritual thought process, which is the result of millions of years of natural evolutionary mechanism which changed our DNA coding and make it human DNA, which put us on the apex of the animal kingdom. All the thought processes religious, cultural, scientific and philosophic are the parts and offshoots of this highly evolved thought process.
