This is an invaluable Vault of books/videos that I have found to be the perfect books for spiritual development. There is a lot of information out there, a lot of it is nonsense, or at the very least non productive. This list of resources are the best books on astrology and spiritual development that i have found in the last decade, no surprise most of them are old and rare books. Im so grateful to have been lucky enough to find them, i hope they are as enlightening to you as they were for me
