If it was "translated and changed in the process" then how does anyone know what the truth really is? And which church, if any, teaches "the truth" today?
No scripture or church can tell you the whole truth, not even one. Everything exists because of its counterpart.
The only truth is the living truth inside each of us, the inner-most self.
In the great work of Nietzsche “Thus spoke Zarathustra”, the last message from Zarathustra to his disciples was: “Be careful with me. I have told you everything I had to say. Now be careful with me. Don´t follow me; forget about me. Let me and go away.”
This is the last message from all the great masters. No great master want to turn you into a puppet, because he would be killing you. He would be a Killer. He will help you be yourself. The master means a chance for you, to be yourself. Only the small minds, the narrow minds that pretend to be masters and aren´t, will want to impose over you.
