Agrippa's classic work on ceremonial magic, The Occult Philosophy volume 3.

In the conclusion to Book Three — Ceremonial Magic, of the Occult Philosophy, Agrippa delivers a somewhat generic tirade, essentially suggesting that if readers find his work confusing, it's because they lack the necessary wisdom to understand it.

However, he drops hints about an arcane knowledge that only the wise can discover by connecting the dots. He discusses ceremonial methods for performing magical rites and emphasizes the importance of the inward and outward preparation for practicing magic. He touches on various topics but stands out when discussing prophecy and prophetic dreams, suggesting that Book Three is about becoming a vessel for personal revelation.

Agrippa's unique aspects in this book include his fluid use of terminology, moving between 'God' and 'the gods,' and his emphasis on silent contemplation as the best form of prayer. His work hints at a more democratic approach to personal, transformative experiences of God or spiritual revelation. Agrippa's work opens up discussions about the relationships between rediscovered Paganism, Renaissance Neoplatonism, the emergence of modern science and philosophy, and religious controversies of his time. In summary, his work is attractive for its ecumenical and mystical approach to understanding and experiencing the divine.
