The philosophy of western occultism. Much of what we consider of the occult is a mirror reflection of long old practices of the east. Only difference is the termology. For example chakras come from Hindu tradition however all cultures share the same focus points of energy especially concerning the brow ( the "third eye"). The only thing new about that new about that idea is the name for it. For thousands of years people have often used symbols or a gem of some sort to amplify their "sight". This very practice wasn't limited to just Hinduism. The very same runs true for Shamanism and necromancy. Both of those paths run very deeply in all paths in one fashion or another. More often than not they interwine via path working or the manner of how they work with spirits. However in western occultism these two paths often get slummed into their own group and there's very little understanding of either at their core
Where as a lot of the older cultures understood the universal base that they run. However the more modern occultists over look the the connections that are clearly there. Western occultism really isn't bring anything new to the table other than very old ideas into the lime light. You rarely see the undiscovered with the "new age" but something rather that has been preached since the beginning of time. And the more you read into different areas the more you'll find that the ideas behind healing to the philosophical understandings are found in another culture. That's not to say that it doesn't lay a solid foundation for understanding, however one most go past the "new age" to see where it stems from. One thing I have personally learn from studying occultism is to understand your own path , you have to branch out into different paths. In short learning path working while staying rooted in your own path. In opinion that's the one thing Western occultism teaches and what a majority of writers from Alice Bailey to William Butler Yeats discussed in their work. As eccentric as some got the bottom line was still the same. Following the universal patterns to find the answers they sought after. Thus making it clear as day the very principal in the what some call new is just a revitalization of something that's far older than the "spiritual revolution" that started in the mid to late nineteenth century. However that's the birth of what we consider modern magick and occultism.
