Attached To The Pure

My grandfather, the Yehudi Hakodesh of Pshyscha zt"l, was known to quote the Mishnah (Keilim 12:2), "All that is attached to the pure is itself pure." His disciple, Rebbe Simcha Bunim once commented that this seemed unfair. Why is it that the tzaddik must struggle his entire life to purify himself, whilst his disciple can simply attach himself, and thereby achieve the same purity? The Yehudi Hakodesh answered that to be attached to a pure tzaddik is often more difficult than becoming pure oneself.
