The dark dual of sun (sunB) could be a neutron star or a black hole. It would alter by relativistic effects, the beam of light-radiations emanating from the grand center (hypotethically, Sagittarius A* at the galaxy hub).
The same relativistic effect could exist in the astral dimension, where the spiritual, astral light of the grand center would be distorted and counteracted by the astral mass of sun B.
After reading Frawley i concur with you as I have already said: We can ascertain from reading these two paragraphs (see Frawleys' quotes above) that Vishnunabhi is synonymous with the galactic center (hypotethically, Sagittarius A* at the galaxy hub" ~mccoy). we can see it matters little that our proximity to the Galactic Center is negligible in a 24,000 year period. What is more important, however, is the obscuring nature of our 'dark companion' Because it obscures the galactic center in Sagittarius. This magnetic field he speaks of that obstructs the light would be an important answer to the unexplained challenges to the procession of the equinoxes being caused by the conventional view that the earth wobbles. Frawleys' view (above) is the best explanation, so far..... for me. Although it may not be an accurate one, or a final explanatiion.
