Just reminded me of an old story about Dr Wallach who used to place his big yarmuka over his eyes whenever he was called upon to treat a female patient. When R Shmuel Salant the rov of Jerusalem heard about this practice, he told him that he must stop it, for it may interfere with giving proper medical care.
He also said to him that if the Dr does his work for the sake of Heaven the he Rav shmuel Salant guarantees him that the YH will never overcome him and no "thoughts" will befall him.
I dare say its a pretty safe bet that the great tzadiks guarantee to Dr Wallach applies to kanesher as well.
