Thought this might be interesting; To see visually the power of the middle of the Milky Way. If indeed there was some obstruction from the source of the middle of the Milky Way it does appear that it may affect the consciousness of the inhabitants in a small solar system on one of the arms of our galaxy.
That is the Frawley hypothesis, which proposes the existance of a spiritual 'light' emanating from Sagittarius A*, the central black hole in our galaxy. He believes that an obstruction, another celestial object, may prevent this influence ('light') to reach us at times, causing recurring dark ages.
I think the model is too vague and undefined. Which would be such an obstruction? A single celestial body or many? Which is or are the spatial patterns and configurations causing such an obstruction? Sagittarius A* is a fixed benchmark in this respect, so it shouldn't be too hard to point out possible 'obstructions'.
It probably will take more interest from the astronomy and scientific communities to come up with a model that makes sense. Many if not most in those communities still accept the wobble theory of our planet to explain the procession of the equinoxes so it may take a while before that happens and an acceptance of a binary system manifests for the retrograde motion of our solar system through the astrological signs. Although they have already found out that there are mutations and anomalies that can't be completely explained by the wobble of our earth. We should also accept the fact that at the time of Sri Yukteswar living in the body there most likely was no understanding or concept of the center of our galaxy. Therefore he used a word like Vishnunabhi to designate it in his own terms. That's my take on it. We did not have the technology to have pictures and an understanding of our universe-though small- as we do today.
