Motoöri and Hirata account for the invisibility of such Gods as Musubi, the God of Growth, by the theory that since the Age of the Gods they have removed further from the earth, so that they are now beyond the scope of human vision. In other respects, however, they have, under unacknowledged Chinese influence, greatly developed the hints of the spiritual nature of the Gods which are found in the _Kojiki_ and _Nihongi_. Of the _mitama_, Motoöri says[16]:-- _"In general, when such or such a God is mentioned in the old scriptures, we must distinguish between the real God and his mitama. The real God is his actual body; the mitama is his divine spirit: the mitama-shiro (spirit-token) is the thing, be it a mirror or aught else, to which the divine spirit attaches itself. It is commonly called the Shintai (God-body). Now both the real body and the spirit are spoken of simply as the God. Thus when we are told that Amaterasu no Ohokami was entrusted to Toyo-suki-iri-bime and Yamato no Oho-kuni-dama to Nunaki-iri-bime, it is not to be supposed that the real bodies of these two deities were in the Imperial Palace. It is unquestionably their mitama-shiro which are spoken of as if they were the real bodies.... Again, when we are told in the history of the same reign that the Mikado assembled the eighty myriads of Gods on the plain of Kami-asachi and inquired of them by divination, this is not like the assembly in the divine age of the real Gods in the Plain of High Heaven. The invitation is to their mitama."_ The same writer says that of the attendant deities who came down from Heaven with Ninigi, some came in their real bodies, some as _mitama_. Among the former he naturally classes all those who are represented as having human descendants. Hirata regards this as a discovery which will endure to all ages. The following quotation from Hirata's _Koshiden_ (vi. 9) illustrates further the ideas of this school of theology regarding the spiritual nature of the Gods:-- _"Both this God(Chigaheshi) and Kunado[17] were produced by the great mitama of the great God Izanagi applying itself earnestly to preventing the entrance into this world of the things coming furiously from the Land of Yomi, and which accordingly became separated from him and adhered to a staff and a stone. Remaining there, it (the mitama) did good service in both cases. These Gods, moreover, sometimes reveal their real bodies and dispense blessings. This may not be doubted. We find below that Kunado no Kami acted as a guide to Futsunushi; and that Chigaheshi no Oho-Kami was two deities distinguished as hiko and hime (prince and princess)."_
