our podcast: Within Orb

Clocking over 20K downloads and counting, Within Orb is our premiere podcast dedicated to exploring the books and texts that have changed our lives, as we grow our astrological practice. Tune in every week to hear our host and founder, Jenn Zahrt, interview a new voice in the field about the books (not always astrological!) that changed how they work with celestial arts.

We’ve interviewed luminaries such as Thea Anderson, Camm Cassidy, Adam Sommer, Nick Campion, Rod Suskin, Azur César, Kira Ryberg and others on the way. If you know someone you’d like to see on the show, get in touch!

You can subscribe via your favorite podcatcher, or head over to our YouTube channel to listen to a few of the full conversations via video. 

We hope you enjoy these deep dives into the texts that shape how we think and work with the starry firmament here on Earth

“It is impossible to talk about astrology as a monolithic entity, unchanged since ancient times and the same from culture to culture … under the general rubric of astrology there are competing methodologies, a diversity of techniques, and a variety of underlying philosophies.”
