The lower and the upper semicircles of the Yi-globe,
where the hexagrams are shown in plane, best serve for direct comparison. There, the structural features common with the yantras are clearly visible: the arrangement of the hexagrams around the center, the concentric circles embedded into one another, and the perfect balance and symmetry.
The analogy between the Yi-globe and the yantras can be recognized in almost every formal detail, if the Chamunda-yantra (Yantra literally means “support” and “instrument”. A Yantra is a geometric design acting as a highly efficient tool for contemplation, concentration and meditation carrying spiritual significance) is taken as an example
The similarity between the two symbols is still more complete with respect to the metaphysical contents. Yantras are the symbols of deities, whereby one part represents a god (generally, a goddess) itself, while the other part stands for the cosmic activity (function) attributed to the deity and the power manifested in the latter; thus actually, a yantra symbolizes the whole universe as well. The power of the yantras lies in the concentrated visualization – completed with the vibration of the associated mantras – capable even in itself of raising and directing cosmic energies into the human psyche, whereby man merges into the deity in his mind and, at last, becomes one with the universe, the cosmic wholeness.
When the properties of the two symbols are analyzed, the following cosmological analogies between the Yi-globe and the yantras are found
The comparison clearly reveals that the Yi-globe and the yantras represent the same spiritual content and that most of their formal elements are identical as well. Accordingly, it is fully justified to take the Yi-globe as a special yantra.
Figure below demonstrates how easily the Yi-globe transforms into the form of a yantra. Since this yantra perfectly reflects all the connotations of the Yi-globe, its name is Yi-yantra.
On the petals (or other geometrical elements) of the yantras, mantras are written. On the Yi-yantra, the hexagrams replace the mantras at the corresponding places. (This replacement is merely formal here, since the function of the mantras manifests only when they are expressed in words.)
Based on the exposed analysis, the connotations of the individual geometrical elements in the Yi-yantra are as follows:
- The two circlets in the center stand for the two signs of Completion, representing the Center of the World, the starting point of creation, and at the same time the place of final dissolution.
- The creative forces, which are to give birth to the macrocosm and microcosm, emanate from the center. This process is represented by the hexagon.
- The eight double trigrams surrounding the hexagon represent the differentiated primal powers arranged according to the Earlier Heaven. The two squares show that they already embrace the created world, but only in inherent (i.e., not manifested) form.
- The red circle around the squares unites the ten hexagrams on the axis of the Yi-globe. The parallel blue circle is level I of the Yi-globe, whereto the powers of the Receptive extend, and wherefrom changes (forces) direct outwards in the direction of level II. The six orange petals of the lotus (the six hexagrams) show these directions.
- The next pair of the orange and blue circles, and the twelve orange petals with the twelve hexagrams stand for levels II.
- The next circle contains eighteen orange petals, representing level III. At its outer circle, the development (evolution) ends. On level III, the golden petals show the opposite direction of the movement.
- From here, the development is directed inwards (involution). The way goes through levels IV and V, to the final dissolution in the Creative in the Center.
- The square surrounding the Yi-globe represents the external existence; its gates provide access towards the inward world. The square area stands for the created world, shown by the trigrams indicated therein and arranged according to the Later Heaven.
