CAELi is an institution for diverse and in-depth study of astrology for both scholars and laypeople. Founded by the need to have a space to read, study and to dive deeper into contemporary and historic celestial study, CAELi is an incubator for new ideas and cutting-edge research in the field.

Introducing our podcast: Within Orb

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, Clarissa Dolphin, Camm Cassidy, Adam Sommer, Mj Patterson, and many more 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 watch 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.

Plus: triple Ganesh song bursts, philosophical musings on time in the Vedic tradition, and teaching you how to think!

“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.”
