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.
