At Katsuragawa Sokushō Myōō-in in Shiga, a legend tells that the monk Sōō carved a statue of Fudō Myōō from sacred wood obtained from a waterfall’s basin. Such beliefs linking waterfalls and the Myōō are widespread in Shugendō and Tendai circles, with tales across Japan describing waterfalls as sacred sites where the deity descends. Sekien’s image is understood as a visualization of these waterfall-deity epiphanies, showing a figure emerging from the plunge pool to subdue evil, though no specific oral tale is attached to it.
