Herman Constantin Vetterling (2 August 1849 – 5 September 1931),[1] also known as Herman Carl Vetterling and by the pseudonym Philangi Dasa,[2] was an American Swedenborgian philosopher who converted to Buddhism in 1884 and took the Arabic-cum-Sanskritic name Philangi Dasa (meaning "Western Devotee").
Vetterling was born in Pjätteryd, Kronoberg, Småland, Sweden, and emigrated to the United States in 1873. He was naturalized in Philadelphia in 1880.[3] He was one of the first Americans to officially embrace Buddhism.[2] He founded The Buddhist Ray in Santa Cruz, California in 1887, which was the first Buddhist journal in the United States.[4]
His best known work was Swedenborg the Buddhist, or The Higher Swedenborgianism: Its Secrets and Thibetan Origin, published in 1887. It is a fictional spiritual dialogue between Swedenborg, a Buddhist monk, a Brahmin, a Parsi, an Aztec Indian, an Icelander, an anonymous woman, and Vetterling himself. Six years later this work was translated into Japanese.[5]
Due to his eclectic combination of Swedenborgianism, Theosophy, Buddhism, homeopathy and Spiritualism, many scholars of his lifetime questioned his authenticity as a "real" Buddhist.[2]
