I remember reading a comment about how in Vedic Astrology the nodes could indicate a grandparents profession, but I haven't been able to find information about it. I'd like to know more about this, thanks.
The Nodes of the Moon not only indicate grandparents but have deeper meanings. Since they donot have physical existance and are just shadows, they act like reflecting bodies in my own terms. If conjunct to some planet, they act like that planet, if aspected by some planet, they become a representative of that planet. Also they give the results of their constellation lord during their periods.
