If you have a Fixed Star on a personal planet( Sun, Moon, Mercury, Venus or Mars) you have the finger of destiny pointing towards you. The Fixed Stars are unique, in that they can be good, bad or a choice between the two. The choice is the scary part.
Aldebaran is one of the Fixed stars that could go either way. The Fixed Stars are fixed in place. Aldebaran is at 9 Gemini.
I have it conjunct Venus. Aldebaran offers a choice, in that you could achieve great honors or you could go down into debasement. However, it would be by your own hand! That seems to be the case with the Fixed Stars which do offer choice.
Check out your own. In the meantime, I will research more and write about them, as I do. My best teachers are your experiences, so Google Fixed Stars and see what you have. Do you feel an affinity with any of them?
