Drawing the Sri Yantra by hand
The Sri Yantra looks simple from across a room. Nine triangles interlock around a central point, inside two rings of lotus petals, inside a square with four gates. Then you try to draw it, and you discover that it is one of the hardest figures in the whole tradition to get right.
The structure
Four triangles point upward and are read as Shiva, consciousness. Five point downward and are read as Shakti, power. Their overlaps produce forty-three smaller triangles around the central point, the bindu. The whole figure is read from the outside in as nine enclosures:
| Enclosure | Form |
|---|---|
| 1 | The square, with four gates |
| 2 | Sixteen-petalled lotus |
| 3 | Eight-petalled lotus |
| 4 | Fourteen triangles |
| 5 | Ten outer triangles |
| 6 | Ten inner triangles |
| 7 | Eight triangles |
| 8 | The central triangle |
| 9 | The bindu |
Each enclosure has its own goddesses, its own mantras and its own stage in the practitioner’s journey inward.
Where it goes wrong
The difficulty is that the lines are not independent. In a well-drawn Sri Yantra, three lines meet at a single point again and again across the figure. Move one triangle’s base by a hair and a dozen intersections drift apart into tiny slivers.
There is no simple construction that makes every crossing exact. Draftsmen have worked out approximations for centuries, and mathematicians still write papers about it. By hand, the honest answer is patience.
How I draw it
- Lay down the centre line and the circle that will hold the triangles. Everything is measured from these two.
- Mark the heights of the triangle bases along the centre line before drawing a single diagonal.
- Draw the largest downward triangle first, then the largest upward one. Check every crossing with a loupe before continuing.
- Work inward, one pair at a time, correcting the marks as the errors show themselves.
- Only when the triangles are settled, add the lotus rings and the square.
A careful drawing takes me most of a day. The first few I made took a week and went in the drawer.
I used to think the errors were a failure of craft. Now I think they are the practice. The yantra asks for a kind of attention that cannot drift for even one line, and it shows you, with complete honesty, the moment that it did.
