As the citadel vehicle begins to manifest within the immediate field of the soul we become aware of its immensity, its forbidding power and deep immovability. Its upper part is diamond solid gold, and its base is diamond platinum. The sense is of solidity and immensity, power and invulnerability. It can fill the whole body, or become as immense as a mountain. Gold is the substance of essential truth; diamond gold is the objective wisdom of essential truth. Platinum is the aspect of universal will, the will of true nature toward optimization and realization, so its diamond is objective wisdom of this support. Thus the central body of the citadel is objective universal support for objective truth, and its teaching is the recognition how to live one's life in a way that harmonizes with true nature’s universal will, which is inseparable from objective truth. The citadel is an immense presence, dense and immovable.
