In our existential worlds nothing can enter our consciousness before its time. It first becomes rejected because it is seen as a threat to the established structures built on the relative known. We as our structures oppose the new because our structures are based on the past.
We live in the past; even the future we perceive is an ongoing projection of past. The fear of the unknown prevails and so it continues through sequential events until eventually the unknown partly unfolds when the time is right.
History demonstrates this fact. When Galileo dared to voice that our planet was not as then believed, he was ostracized by the power structures and obliged to refute his discovery. The prophets faced the same issue, the structures of their time banishing them, like the followers of Jesus driven underground by the interpretative minds creating their own version of his life and events as a means for restructuring control, peace upon all of them. It is exactly the same today. Our scientists are our new high priests, still trapped within the narrow confines of mind.
