The Indian tradition has many geometric figures used as supports for meditation and worship, called yantras. Of them all, the Sri Yantra (or Shri Chakra) is considered the most important and the most refined. At first sight it looks like a dense web of triangles enclosed by petals and a square boundary; on closer inspection it reveals a rigorous construction in which every element has its place and meaning.
What a yantra is
The Sanskrit word yantra comes from a root meaning to hold, to support, to control: it is an «instrument». In a religious context it is a diagram that represents a deity or an aspect of the divine in geometric form, without human figures. If the mantra is the sound form of a divine power, the yantra is its visual form.
The Sri Yantra belongs in particular to the current called Shri Vidya, which worships the Goddess in the form of Lalita Tripurasundari, «the beautiful one of the three worlds». For practitioners of this tradition the diagram is not an image of the Goddess: it is the Goddess herself in her geometric manifestation.
The structure from the centre outwards
The Sri Yantra is read as a series of concentric enclosures. Tradition counts nine of them, called avarana, «coverings» or «enclosures».
| Level | Element | Description |
|---|---|---|
| Centre | Bindu | the point, origin of all things |
| Core | Central triangle | the first triangle, pointing downwards |
| Interlacing | Smaller triangles | the triangles formed where the nine large triangles cross, arranged in four rings |
| Flowers | Two crowns of petals | a lotus of eight petals and one of sixteen |
| Circles | Three circular lines | rings separating the petals from the enclosure |
| Outside | Bhupura | a square enclosure with four gates |
The bindu is the dimensionless point from which, according to tradition, the whole universe unfolds. The bhupura, the square enclosure with gates facing the four cardinal points, marks the boundary between sacred space and the outside world. Between these two extremes all of manifestation unfolds.
The nine triangles
The heart of the figure is formed by nine large overlapping triangles:
- four pointing upwards, associated with the masculine principle, Shiva;
- five pointing downwards, associated with the feminine principle, Shakti.
Their interlacing generates, by the traditional count, forty-three smaller triangles, which together with the bindu make up the inner levels of the diagram. The symbolic idea is clear: the world is born from the union and interpenetration of two complementary principles, and neither exists in isolation from the other.
In Indian symbolism the downward triangle recalls the womb and generative power; the upward one recalls the flame and rising consciousness. The numerical predominance of the feminine triangles underlines the character of this tradition, centred on the Goddess as the energy that creates and sustains.
An extremely difficult layout
Anyone who tries to draw a Sri Yantra with ruler and compass soon discovers that it is not simple at all. For the figure to be correct, many lines must meet at exactly the same point: at several crossings three lines must pass through a single vertex. A small error in the position of one triangle is enough to shift the following intersections and make the figure lose its coherence.
This is why traditional manuals give precise instructions on how to divide the vertical axis and where to place the bases of the triangles, and why the Sri Yantra has also attracted the interest of modern mathematicians, who have studied the conditions for its construction. The difficulty itself has a symbolic value: harmony does not come from approximation, but from an exact balance of all the parts.
The forms of the Sri Yantra
The Sri Yantra can be made in various forms:
- Two-dimensional, drawn, engraved on metal or painted.
- Three-dimensional, called Meru, in which the levels rise progressively up to the bindu, like a sacred mountain seen from the side.
- Inner, visualised in meditation without any material support.
The mountain form recalls Mount Meru, the axis of the world in Indian cosmology. The path from the bhupura to the bindu thus also becomes an ascent: from periphery to centre, from the many to the one.
The path through the enclosures
In the ritual practice of Shri Vidya, contemplation of the Sri Yantra often follows an order: one starts from the outer enclosure and moves inwards, crossing one enclosure after another, each associated with different deities and states of consciousness. The movement represents the soul's return to its origin.
Even without adhering to this religious tradition, anyone studying sacred geometry can grasp a universal model in this structure: the centre as origin, the enclosures as degrees of manifestation, the gate as passage. It is an idea that Maestro Cornelio invites us to observe in many sacred forms, from temples to mandalas, as a common language of the human spirit.
In short
- The Sri Yantra is the principal sacred diagram of the Shri Vidya tradition, dedicated to the Goddess Lalita Tripurasundari.
- It is formed by nine interlocking triangles: four pointing up (Shiva) and five pointing down (Shakti).
- Around the interlacing lie two crowns of petals, three circles and the square enclosure with four gates.
- Drawing it exactly is very difficult, because many lines must meet at the same point.
- The three-dimensional form, called Meru, turns the path from edge to centre into an ascent.
