Steve, I'll have to listen to it again, what I remember is that, if we take an unconventional theory as a reference for the solar system velocity compared to the fixed stars, then we could include Sirius as a candidate for the dual star. I kind of missed the Pleiades piece, I'm usually listening to podcasts while driving my son around, and he sometimes will play his portable keyboard at full volume. Sometimes I just miss parts of podcasts.
In my understanding he is still placing The Pleiades as the dual where Alcyone is the brightest star. Alcyone is 440 light years from us. Sirius is 8 light years. So apparently we share some motion similar to Sirius while traveling around Alcyone. It really fascinates me because if it were true it would explain so much about history and verify so many of Yogananda’s writings.
I listened to the podcast a second time. My interpretation is that he mentions the Pleiades as the grand spiritual center (probably an astral object) which emanates spiritual vibrations.
The sun, while rotating around its dual, in this hypothesis Sirius, oscillates between a closer and a further orbital distance (from the Pleiades), with respectively more spiritual influence and less spiritual influence from this spiritual center.
I would like to know which is the difference in orbital distances. If the Pleiades are 440 light-years distant, an orbital delta of twice the distance of Sirius, as an example, = 16 LY, would be equal to 16/440 = about 4% difference with respect to the total distance of the Pleiades, which is maybe too a little amount to explain all such difference in the spiritual vibration. It would be like saying, any civilization closer to the Pleaides than the earth would be ultra-Uber-evolved. But we have no sign of such civilizations.
This kind of reasoning is what convinced me that the galactic hub si probably not the grand center.
So, from the above, it seems unlikely to me that the Pleiades are SY's grand center. Cruttenden cites the Pleaides since his interest is archaeoastronomy, sharing Tara MAta's interest. But the number do not seem to agree with such hypothesis.
