both of them are so wet that the wetness of one of them contacts the other, the pure thing alsobecomes impure. Similarly if the wetness of the thing which has become impure in this way touches a third thing that third thing will also become impure. And the well-knownremark of the religious scholars is that the thing which becomes impure owing to its contact with an original impurity can makes the other thing impure (i.e. an impure thingmakes other things impure whether it became impure owing to its contact with another thing which had become impure or had become impure directly due to contact with anoriginal impure thing). Nevertheless, it is difficult to apply this order to those things which have not acquired impurity from the fîst impure thing, although it isnecessary to avoid them as an obligatory precaution.

However, if after becoming dry, the left hand touches under-Kurr water, that water will also become impure. However, if that handtouches another wet thing it is difficult to say that thing will become impure, although, oh the basis of obligatory precaution, it is necessary to avoid that thing. And ifthe wetness is so little that it does not reach the other thing being touched the pure thing will not become impure, even if it touches the original impurity.
