In the section 39, 'the story of Matarashin in Jogyo-do Hall' of the "Keiran shuyo shu" (a collection of oral transmissions in the Japanese Tendai Sect which contains four stories about Myoe), there is a description that Ennin, a priest of the Tendai Sect, learned Inzei Nenbutsu (Chanting of the Buddhist invocation with a prolonged voice) of the Mt. Wutai Shan in China (Tang), was inspired upon hearing Matarashin's voice from the air on a ship to go back to Japan, built the Jyogyo-do Hall on Mt. Hiei, performed kanjo (ceremonial transfer of a divided tutelary deity to a new location) and Jogyo-zanmai (absorption in walking around Amitabha, invocating his name and nenbutsu), and began believing in Amitabha.
『渓嵐拾葉集』第39「常行堂摩多羅神の事」では、天台宗の円仁が中国（唐）で五台山の引声念仏を相伝し、帰国する際に船中で虚空から摩多羅神の声が聞こえて感得、比叡山に常行堂を建立して常行堂へ勧請し、常行三昧を始修して阿弥陀信仰を始めたと記されている。
