This stands as one of the most important books Ive read about the nature of reality and the supersensible universe. As with any work intending to teach through words something that is larger and exponentially more complex than language will always require careful study. And though this book is not long by page standards, it requires careful, slow study if one is to get the maximum weight of the material.If you are unable to let go of the question of whether there is more to the universe than meets the eye, this should be on your reading list.
If the idea of supersensible realms of experience do not drive you, or you think the idea of anything that cannot be seen with the objective eye is absurd, save yourself time and dont bother with this.For me, this may stand as the most important piece of instruction Ive received, even though I feel like I understood most of the ideas before. This work neatly organized and illustrated the differences between seemingly similar phenomena like vibration and rhythm, polarity and correspondence, etc.
Id give it 7 stars if I could. --)
