Astrology's Hidden Aspects: Quintiles and Sesquiquintiles

As usual Dusty has published another great book chock full of info!! I use these aspects in the charts I run so I suggest students purchase this book! Thank you Dusty!

As someone who swears by the 5th Harmonic, I highly recommend this book. The author discusses mathematics, geometry, and philosophy in great depth and uses universal principles to elucidate the importance of the 5th Harmonic, the Sacred Golden Bowl. I love this book.

Great reference book for other aspects not covered in most astrology books

We've been using this book in class for a month or so now and have gained lots of insight into quintiles. if you have quintiles in your chart, this is the place to find guidance on their meaning and influence in your chart.
