A verse from Shvetaashvatara upanishad

[Guest guest]

Dear indologists,

 

Shvetaashvatara upanishad has the following verse

1.4 tam ekanemi.n trivR^ita.n shhoDashaanta.n

shataardhaara.n vi.nshatipratyaraabhiH

ashhTakaiH shhaDbhir vishvaruupaikapaasha.n

trimaargabheda.n dvinimittaikamoham.h

 

This verse is translated by Max Muller as

 

4. We meditate on him who (like a wheel) has one felly with three tires, sixteen

ends, fifty spokes, with twenty counter-spokes, and six sets of eight; whose one

rope is manifold, who proceeds on three different roads, and whose illusion

arises from two causes.

 

Other thranslations I came across are very similar.

 

I have two questions:

 

1. Is there a depiction of this image (three tires,sixteen ends, etc.) that

reflects all of the components numerically correct?

 

2. Is there any interpretation of this description being a symbol of

some other than a wheel structure?

Whar are all those spokes, counter spokes, one-rim but three circumferences?

What are those six sets of eight?

 

Thanks in advance,

Dmitri.
