A mystic atmosphere is the first impression the visitor has while entering this cozy, scented Hall, where nine lit spheres diffuse a soft-colored light all around. The alchemic liquids they contain have been patiently distilled and represent the maximum concentration of elements and memories that can allow us to contact the subtle forces of our planet and the universe.

The ceiling and the walls are covered with gold leaf, keeping a high level of vibrational frequency inside the Hall. At the sides of the niches in which eight spheres are contained, a beautiful wall mosaic is the background to pedestals, sculpted out of young stone and representing winged chimeras, that support chalices made of precious metals. The chalices are reminiscent of the Grail, as the container in which the universal alchemic transformation takes place.

At the far end of the Hall, inside a recess excavated into the rock, a marble altar supports the ninth sphere. On the walls, at the four corners, an oil-based pictorial cycle is dedicated to the divine masculine and feminine forces. At the center of the gray-red marble floor, the design inside a diamond shape is that of the soul structure, as the Damanhurian philosophy conceives it.
