This compilation was published in French in 1976 by the National Spiritual Assembly of the Bahá’ís of Switzerland, from French translations available at the time. In 2025 P. Spierckel translated anew the selections from Abdu’l-Bahá from the updated English versions, accompanying new translations of the selections from the Writings of Bahá'u'lláh by the French Panel, also from the updated English.
