Jyotish represents the eye, one of the Vedangas, of the Vedas.
What does this mean?
I think there is a lot to think about here.
For one, tamas, the guna to avoid, translates first to “darkness”, not beeing able to see, that is, the absence of light. Jyotish is light, is seeing.
The eye is a lens, used to look outward and to separate “me” from “them”, the basis of our Ahamkaara.
“The illusion that we are separate from one another is an optical delusion of our consciousness.” – Albert Einstein
What we see feeds our personality internally, makes the inside and out seem separate. From the transient ephemeral “outside” our eyes determine the individuality of our faces and the individuality of our experiences.
Eyes are the window to our soul it is said, but then, how could the VEDAS have eyes?
One lens that is the chart to an Ahamkaara can be seen as that Ahamkaara itself. Signpost, signed, and signer, the jiiva or being can be seen as accurately via a chart as being looked at directly, if through the eyes of a proper reader.
As skilled astrologers know, that same chart can then be a lens to see other jiivas.
Indeed all is One, OM TAT SAT, and the proof is in any given Jyotish chart.
