People think that Nostradamus was trance connector who communicated with supernatural beings and spirits to make the future predictions. There are also believes that he used special methods in his foretelling such as spirit guide, hosting him in the body and asking him about future events. The astrologer used two main methods to come to an unconscious state called trance- one of them is staring into a flame, the other- staring into the water. Nostradamus also followed some practices of Oracle of Delphi; he sat feet flat on the floor with a straight spine on a stool (tripod) whose legs were angled at the exact degrees as the Egyptian pyramids. This stool was intended to make an electromagnetic power to open the door to the Supernatural.
This process is described in his quatrains of Century 1:
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.
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, feat: he trembles in his robes.
Divine splendor; the God sits nearby.
In his prophetic work he placed a bowl with water and special oils on a tripod, and nutmeg considering that they were making the process of coming into trance easier. Nutmeg was used as a hallucinogen.
In his famous letter to Henry the second, Nostradamus wrote about his prophetic work: “I emptied my soul, brain and heart of all the care and attained a state of tranquility and stillness of mind which are prerequisites for predicting by means of the brass tripod”.
We can consider the methods, used by astrologer doubtful, still they exist even nowadays and used by famous prophets.
