The 12 constellations of the zodiac are the 12 doors of our universe, and these same 12 doors are found in our physical body

"The twelve constellations of the zodiac are the twelve doors of our universe, and these same twelve doors are found in our physical body. Yes, for our eyes, ears, mouth and nostrils, as well as other orifices lower down, are also doors. And just as the doors of the zodiac serve as passageways for cosmic influences, so the doors of our body permit the passage of forces and spirits.

Those who have carried out a real work of purification in themselves make contact through the doors of the body with the subtle, luminous elements present in space. This is why, according to initiatic tradition, an angel stands guard at each door. An angel is pure energy, energy which not only attracts beneficial influences but transforms the negative currents which attempt to infiltrate us. Angels watch over the doors of all who have worked to make their entire being a tabernacle of the living God."
