The power of Yantras to induce RESONANCE is based on the SPECIFIC FORM of its appearance. Such a diagram can be composed from one or more geometrical shapes which combine into a precise model representing and transfiguring in essence, at the level of the physical universe, the subtle sphere of force corresponding to the invoked deity (God). By RESONANCE, a certain energy from the practitioner's MICROCOSM vibrates on the same wavelength with the corresponding infinite energy present in the MACROCOSM, energy which is represented in the physical plane by the Yantra. The principle of RESONANCE with any deity, cosmic power, aspect, phenomenon or energy owes its universal applicability to the perfect correspondence existing between the human being and the Creation as a whole (Universe).
