shrI yantra with spherical triangles

[Guest guest]

I was reading Joseph's discussion of shrI yantra at:

http://alumni.cse.ucsc.edu/~mikel/sriyantra/joseph.html

 

where he says that there are some shrI yantras with

spherical triangles (triangles drawn on a spherical surface)

rather than on a plane. This is intriguing because spherical

traingles are used in positional astronomy, to determine

the positions of celestial bodies. In positional astronomy,

the observer is supposed to be placed at the center of the

celestial sphere. The observer can then measure various

angles in different reference systems to determine the

position of a heavenly body. Also, note that positions in

spherical astronomy are usually given in angles, not linear

distances. So the question is:

 

Do the spherical triangles in the shrI yantra signify some

celestial bodies (such as stars, constellations, planets) and if

so what are those bodies? Or could it be that the spherical

triangles represent the whole universe, with the bindu

being directly above the sole observer, the sAxI or Atman

which is also the originator of the universe? Note that

the bindu would be on the spherical surface, not at its

center. It could be interpreted as the zenith in positional

astronomy, which is the highest point in the celestial shpere.
