The characteristic of this book is that it emphasizes 'wabi' (an aesthetic ideal that finds surpassing beauty and deep significance in what is humble or commonplace and appears natural or artless), taking the definite stand for Buddhism (Zen sect)-centrism which defines it as 'pure and clean Buddha's world.'
本書の特性は「わび」を強調して、これを「清浄無垢の仏世界」と規定する仏教（禅宗）中心主義の立場を明確にとっている点である。
