Book excerpt: Previously published as At the Gates of Spiritual Science, these lectures offer a fine introduction to the whole of Rudolf Steiner's teaching, as well as including valuable material which is not to be found elsewhere. With great clarity and precision, Steiner speaks of the fundamental nature of the human being in relation to the cosmos, the evolution of the Earth, the journey of the soul after death, reincarnation and karma, good and evil, the modern path of meditative training, as well as giving answers to individual questions.Throughout, Steiner's emphasis is on a scientific exposition of spiritual phenomena. As he says in the final lecture: "the highest knowledge of mundane things is thoroughly compatible with the highest knowledge of spiritual truths."
