“This plant must be harvested at 12:00 midday on Good Friday.
First, the magician will trace a circle around the plant. He will then kneel before it.
Next, he will pray, asking the elemental of the plant for the desired service.
Afterward, he will yank it from its very roots and take it home. The plant must be yanked while the magician is facing toward the east.
By its roots, the plant must be hung on the ceiling of the house, so that the plant remains in a position with its roots aiming upward and its branches aiming downward. The plant must remain toward the east. The power of this elemental will grant unto its owner whatever was asked for. “
-Samael Aun Weor, Occult Medicine and Practical Magic
Notes:
