His civil obligations lasted until the next world war. During that period, he resumed lecturing, but declined a teaching contract for Tibetan philology and went on vacation. He brought his vacation to an abrupt end when he was appointed to the position of "extraordinary professor", but ended his academic career in November 1921. From 1920 onwards, he worked as a lecturer of anthroposophy. In March 1922, he joined the "Gründerkreis" (circle of priests) of The Christian Community and worked until his death as a priest, seminary teacher, lecturer, independent researcher and writer. In 1928, Beckh's "Der kosmische Rhythmus im Markusevangelium" ("Mark's Gospel: The Cosmic Rhythm") was published, in which he related the narration of the gospel of Mark to the path of the sun through the twelve zodiacal signs, and mentioned earlier work of Arthur Drews, Eduard Stucken (author of "Astralmythen der Hebraeer, Babylonier, und Aegypter, Leipzig", 1896-1907) and Andrzej Niemojewski. In the Introduction to the sequel, "Der kosmische Rhythmus, das Sternengeheimnis und Erdengeheimnis im Johannesevangelium" ("The Cosmic Rhythm, the Secrets of the Stars and Earth in the Gospel of John") (1930), Beck mentioned favourably Wilhelm Kaiser's "Die geometrischen Vorstellungen in der Astronomie" (1928), and referred to "The Novices of Sais", of Novalis. The cosmic rhythm in Beckh's exposition, he explained, was for Mark's gospel understood more in connection with the "earthly" zodiac of the signs, and for John's gospel more in connection with the "stellar" zodiac of the constellations, while, at the time of the beginning of the Christian era, these were coincident. Beckh died in Stuttgart, in 1937.
