"One of the side effects of eating amanita mushrooms is that the skin and facial features take on a flushed, ruddy glow. This is why Santa is always shown with glowing red cheeks and nose. Even Santa's jolly "Ho, ho, ho!" is the euphoric laugh of one who has indulged in the magic fungus.
Santa also dresses like a mushroom gatherer. When it was time to go out and harvest the magical mushrooms, the ancient shamans would dress much like Santa, wearing red and white fur-trimmed coats and long black boots.
These peoples lived in dwellings made of birch and reindeer hide, called "yurts." Somewhat similar to a teepee, the yurt's central smokehole is often also used as an entrance. After gathering the mushrooms from under the sacred trees where they appeared, the shamans would fill their sacks and return home. Climbing down the chimney-entrances, they would share out the mushroom's gifts with those within.
The amanita mushroom needs to be dried before being consumed; the drying process reduces the mushroom's toxicity while increasing its potency. The shaman would guide the group in stringing the mushrooms and hanging them around the hearth-fire to dry. This tradition is echoed in the modern stringing of popcorn and other items.
The psychedelic journeys taken under the influence of the amanita were also symbolized by a stick reaching up through the smokehole in the top of the yurt. The smokehole was the portal where the spirit of the shaman exited the physical plane.
Santa's famous magical journey, where his sleigh takes him around the whole planet in a single night, is developed from the "heavenly chariot," used by the gods from whom Santa and other shamanic figures are descended. The chariot of Odin, Thor and even the Egyptian god Osiris is now known as the Big Dipper, which circles around the North Star in a 24-hour period.
In different versions of the ancient story, the chariot was pulled by reindeer or horses. As the animals grow exhausted, their mingled spit and blood falls to the ground, forming the amanita mushrooms."
