Rudolf Steiner about Helena Petrovna Blavatsky

One thing that can be said of the writings of Helena Petrovna Blavatsky is this: Only someone who does not understand them can underestimate them. But someone who finds the key to what is great in these works will come to admire her more and more. That is what is significant about these works — the more one penetrates them the more one admires them. It is not the case that there are no mistakes to be found in them. But those who really take hold of life know, if they strive to evermore penetrate these works, that what is therein expressed could only have come from the great spiritual beings who are now guiding world evolution. This is how we must read Isis Unveiled, a book containing truths which, although sometimes caricatured like a beautiful face seen in a distorting mirror, are truly great.

A person who would merely like to speak out of a critical spirit might perhaps say: It would have been better not to give any such distortion. But anyone seeing matters in the proper light will say: If someone places their weak spiritual forces at the disposal of spiritual powers who wish to reveal themselves, and knows that these forces will produce only a distorted picture but that there is no one else who could do it any better, then that person, through their devotion, is making a great sacrifice for the world. All renderings of the great truths are distortions. If someone wanted to wait until the whole truth could be manifested, then they would have a long wait.
