In Shinto, "kannagara" ("way of the kami") describes the law of the natural order. Shinto incorporates morality tales and myths but no overarching, codified ethical doctrine; Offner noted that Shinto specified no "unified, systematized code of behaviour". Its views of "kannagara" influence certain ethical views, focused on sincerity ("makoto") and honesty ("tadashii"). "Makoto" is regarded as a cardinal virtue in Japanese religion more broadly. Shinto sometimes includes reference to four virtues known as the "akaki kiyoki kokoro" or "sei-mei-shin", meaning "purity and cheerfulness of heart", which are linked to the state of harae. Offner believed that in Shinto, ideas about goodness linked to "that which possesses, or relates to, beauty, brightness, excellence, good fortune, nobility, purity, suitability, harmony, conformity, productivity." "Shojiki" is regarded as a virtue, encompassing honesty, uprightness, veracity, and frankness. Shinto's flexibility regarding morality and ethics has been a source of frequent criticism, especially from those arguing that the religion can readily become a pawn for those wishing to use it to legitimise their authority and power.
