Establishing Malkooth

Malkooth or 'Kingdom' is a complex sphere in that it represents several broad concepts simultaneously. It is at once, our feet when the Tree of Life is projected on the human frame (and the knees and base of spine when seated or kneeling); all solid matter, earth, and all material creation. It is our bones, and the marrow they contain is a personal aspect of the Secret Fire. It is important that we have a strong sense of foundation when we talk about Earth and Malkooth, so that in meditation we can remain grounded and secure. The stronger our sense of connection to the earth and our bodies we have, the more energy we can generate and the easier it will be to direct it. It is analogous to trying to build a skyscraper on a poured slab concrete for a foundation verses a four-story subbasement. The better the foundation, the stronger the structure.
Since the Secret Fire is hidden in the Earth, it is good to spend some time, even several years, working through the details of the Pentagram rituals. Cleansing, harmonizing, projecting, and withdrawing the energy represented there into yourself and surrounding area. The North is an especially important area for concentration, in that it is Earth of Earth, and is our hidden gateway to the Secret Fire. Buried in the solid nature of matter, is a underlying vibrant energy that is continually pulsating, giving rise to form and life, and turning energy in matter and matter into energy. This underlying nature is illustrated in, the Sign of Taurus, the zodiacal sigil given to the North. In it we see the Moon crowning a circle with a dot in the center, or the Sun. This combined lunar-solar sign for earthly nature points to the theory that all matter is simply condensed sun light, or hidden fire.
By associating the heaviness of Earth and the underlying heat it contains (the molten, volcanic core) with our feet, knees, and base of spine (and eventually our whole skeletal system), we can begin to experience the literal network creation is formed from . This imagery is reinforced by the statement that Malkooth and Kether are one. By imaging that an unlimited stream of energy is pulsating into and out of creation from the Ain Soph Aur at Kether, and then imaging the same for material creation as you envision it, at Malkooth. All to often the spheres are imagined as being static beings or states, when nothing is farther from the truth. They are alive, dynamic, and constantly interacting with each other and the energy-matter matrix. This interaction is most clearly seen on the Middle Pillar and the central spheres.
