Heaven and earth were never separated.
Although religion presents itself as dogmatic -that is, as possessing an established truth- it has shown throughout history that, in reality, it is based on the search for truth through spiritual laws -those of heaven-. Conventional science, by contrast, seeks truth through physical laws -those of the Earth-. And despite presenting itself as a non-dogmatic institution, it accepts only evidence as proof of truth -as if that were not dogmatic in itself-.That is 110 to say, if one embarks upon the path of scientific truth, one avoids the religious one. Even the most simple religious believer knows that science forms part of religion. Only modern scientists -atheists, prisoners of their own arrogance- have rejected religious truth. And the same thing has happened to all of them as to the German philosopher Nietzsche: they “killed” God and ended up in an asylum. You may ignore the external search, but you cannot abolish inner understanding, unless you wish to end up like our good friend the “Übermensch” and encounter the many surprises that the world of repression has in store.
