"You can see from this, my dear friends, what mischief will be set on foot if the truths of Spiritual Science are withheld. For man will be exposed to the forces of evil, and he will only be protected from it by giving himself up to the spiritual life of the good. To withhold the spiritual life of goodness from men is to be no friend to humanity. Whoever does this, be he Freemason or Jesuit, is no friend to humanity. For it means handing men over to the forces of evil. And there may be a purpose in doing so. This purpose may be to confine goodness to a small circle, in order by the help of this goodness to dominate the helpless humanity who are thus led by evil into the follies of life."

Calendar of the Soul

In 1912 Rudolf Steiner offered a “calendar of the soul” with weekly verses that express how the changing seasons in both the outer natural world and our inner lives help humanity evolve. Download and read the verses in four translations with commentary by Eloise Krivosheia of the Los Angeles Branch of the Anthroposophical Society.
