Prophecies and sending messages to the past could be 2 sides of the same technology. How would a possible communication model look like ?
The receiver - A Prophet that receives divine revelation
How did Nostradamus get information from the occult source? In the very first two quatrains, he described his source of knowledge:
Estant assis de nuict secret estude,
Seul reposé fus la selle d'airain;
Flambe exigue sortant de solitude
Feit proferer qui n'est à croire en vain.
Sitting alone at night in secret study;
it is placed on the brass tripod.
A slight flame comes out of the emptiness and
makes successful that which should not be believed in vain.
La verge en main mise au milieu des branches,
De l'onde il moulle le limbe le pied,
Vn peur voix fremissent par les manches,
Splendeur diuine, le diuin pres s'assied.
The wand in the hand is placed in the middle of the tripod's legs.
With water he sprinkles both the hem of his garment and his foot.
A voice, fear: he trembles in his robes.
Divine splendor; the God sits nearby.
Nostradamus describes the occult activities he indulged in, and how he heard a voice wispering. While being in trance, he heard a voice in his mind. Could it be that Nostradamus was at the receiving end of a communication channel? The occult activities enabled him to connect to the source of his knowledge. What he describes as divine revelation could have been the result of a future science experiment.
In a letter to his son Cesar, Nostradamus wrote:
For by the latter, with the help of inspiration and divine revelation, and continual calculations, I have set down my prophecies in writing. Fearing lest this occult philosophy be condemned, I did not therefore wish to make known its dire import; also fearful that several books which had lain hidden for long centuries might be discovered, and of what might become of them, after reading them I presented them to Vulcan. And while he devoured them, the flame licking the air gave out such an unexpected light, clearer than that of an ordinary flame and resembling fire from some flashing cataclysm, and suddenly illumined the house as if it were caught in a furnace. Which is why I reduced them to ashes then, so that none might be tempted to use occult labors in searching for the perfect transmutation, whether lunar or solar, of incorruptible metals.
If divine revelation and sending message through time are related then it is clear that both the sender and receiver live in a clearly different realities, both live in different worlds formed by their own experiences, perceptions and ideas. Something that complicates communication.
