In 1897, Gräser lived in Diefenbach's commune, Himmelhof, located in Ober Sankt Veit, near Vienna, and embraced his ideas of pacifism, a human civilization in harmony with nature, and a vegetarian diet, while studying art.
Among the settlement's inhabitants included several artists and authors such as Otto Gross, Leonhard Frank, Erich Muhsam, Franziska Countess zu Reventlow, and Hermann Hesse, whom Gräser influenced in his written works.
Although he was expelled from Bavaria in 1919, Gräser migrated with a "new crowd" known as the "crusade of love" with his associate, Friedrich Muck-Lamberty, which was a subject in Hesse's story, Journey to the East.
[3] In 1927, Gräser began public speaking in Berlin's Anti-War Museum, settled in the commune of Grunhurst, and traveled through Germany with his son, Otto Brobohmig, to distribute his writings.
Gräser managed to avoid capture by fleeing to Munich, living in seclusion in fellow poets' attics, and wrote some of his most acclaimed pieces including Siebenmah and Wunderbar.
