“During the days I lay in the prison of Ṭihrán, though the galling weight of the chains and the stench-filled air allowed Me but little sleep, still in those infrequent moments of slumber I felt as if something flowed from the crown of My head over My breast, even as a mighty torrent that precipitateth itself upon the earth from the summit of a lofty mountain.“

– Bahá’u’lláh, Epistle to the Son of the Wolf
