“The Threshold of the Spiritual World” harmoniously complements the books “Initiation” and “Occult Science”. What emerges from this work is a desire to transmit and inspire confidence in the process of evolution, despite the obstacles that the aspirant must overcome. If in Steiner's other books we could feel incomprehensions or doubts, The Threshold of the Spiritual World clarifies certain points already discussed, but above all it allows, beyond knowledge, to receive a fraternal and benevolent understanding to continue one's practice and its research.
 “Where love, where altruism is born in life, we perceive the magical breath of the spirit which penetrates the world of the senses” Rudolf Steiner (The Threshold of the Spiritual World)
