"Know the self to be sitting in a Chariot, the body to be the Chariot, the intellect (buddhi) the charioteer, and the mind the reins." --The Upanishads
Having established a locus for our mind within the sacred space/geometry, connections occur without the interference of overt metaphors or symbols. We can listen/feel the most subtle vibrations, like a spider in the center of its web. Once centered in the grid/web looking inside and looking outside we become aware of a unity of form and function. Consciousness merges with the sacred geometry and the fractal nature of awareness arises. Micro/macro views are self-similar resulting in harmony, balance and equilibrium. Connections arise spontaneously between all nodes on the grid; no single node is dominant, all nodes vibrate together.

In contrast, our mundane awareness is not easily balanced. Each connection we experience competes for our attention/energy. Each node fights for dominance over the others. Life is a discordant cacophony of overt signs, symbols, messages and mythologies with contradictory meanings. Consciousness cannot settle into any locus. Awareness does not feel centered and does not realize the self-similar fractal nature of phenomena. Looking inside yields one view, while looking outside we something totally different; alien and threatening. Although the view outside is disturbing we cannot take our attention from it. After a while we are afraid to look inside.
The opportunity/potential of the Lotus Bowl, Metatron's Cube, or any sacred geometry is that it can become the Chariot of God, the Merkabah. These forms may become vehicles for individual consciousness to connect with our Buddha nature. They transport our mundane consciousness to realms of enlightened awareness - the Pure Realms. During these states of expanded consciousness we open ourselves fully to being connected to all possibilities. We arrive to sit on our Lotus Throne, cup one hand to our ear and listen to the vibrations of the cosmos, the music of the spheres, to the songs of all beings - while in the other hand we gather precious Amrita, the elixir that will make us immortal.
