planets or, develope a
system that will protect us, the natural calamities
like floods, typhoons, sub zero temperatures, will become our big problem in the future, so we need a religion that will guide our conscience from simplistic self survival towards a more holistic view of reality.Our oneness with ourselves and Him is the primary tenets or doctrines of this religion.
