All of nature begins to whisper its secrets to us through its sounds. Sounds that were previously incomprehensible to our soul now become the meaningful language of nature.
Rudolf SteinerJust as an age was ready to receive the Copernican theory of the universe, so is our own age ready for the ideas of reincarnation and karma to be brought into the general consciousness of humanity. And what is destined to happen in the course of evolution will happen no matter what powers rise up against it.
Rudolf SteinerWe have seen that blood united to blood in the case of but remotely connected species of animals, kills; blood united to blood in the case of more closely allied species of animals does not kill. The physical organism of man survives when strange blood comes in contact with strange blood, ... but clairvoyant power perishes under the influence of this mixing of blood, or exogamy.
