It should be noted that in his book titled 'Repose of Souls Theory of Shinobu ORIGUCHI' (Shunjusha Publishing Company, 1990), the author Hirofumi TSUSHIRO maintains that the concept of the repose of souls represents the foundation of Shinto, and that it consists of a greater body of thought than is generally considered to be the case; he stresses that ORIGUCHI's famous Marebito theory (theory of visitation by a divine being bringing spiritual gifts and wisdom) and the theory of repose of souls are interchangeable.
尚、津城寛文は、著作「折口信夫の鎮魂論」（春秋社1990年）で、鎮魂とは神道の根本となる、一般に考えられているよりももっと大きな思想で、折口の有名なまれびと論も鎮魂論で置き換えられる、と主張している。
