Anthroposophy is just like every other religious tradition: a mixed bag.

Some traditions have more undistorted truth and less BS baggage than others.

I would be prone to label anthroposophy one of the best Christian traditions but Christianity itself is composed of multiple traditions for multiple reasons.

The most notable reason is the travels of Christ during the undocumented years.

The other big reason is because that there are Naga teachings in Hinduism, Hindu teachings in Egyptian Kabbalah, Egyptian Kabbalah in Judaism, and Judaism in Christianity.

If you're choosing a "base camp" for cosmology, one could do a lot worse than Anthroposophy but one could also do a lot better.
