 "Ṭahor", by contrast, is defined as "pure" in the sense that the person or object is in a clear state and can/may potentially serve as a conduit for Divine and Godly manifestation.Although "ṭumah and ṭaharah" is sometimes translated as "unclean and clean", it is more a spiritual state than a physical one.Once initiated (for the physical signs that initiate tzaraath, zav and niddah, see below) it is generally immeasurable and unquantifiable by known mechanical detection methods, there is no measure of filth, unsanitary, or odorous affiliation with the state of "ṭumah", nor any mechanically measurable level of cleanliness, clarity, or physical purity for the state of "ṭaharah".
