It Takes One to Know One
The Kohen who burned the Parah Adumah was first made tamei prior to his preparing it. He was not allowed to do the full system of being metaher himself. He was only given an opportunity for tevila in the mikva (He'erav Shemesh- waiting for sunset, was not allowed.)
The Kohanim & Leviim were the leaders of Klal Yisroel. They were the teachers. Yoru mishpatecha l'Yaakov v'sorascha l'Yisroel. When a Yid wanted to purify himself he needed to go to a Kohen. The Kohen would use the Waters with the Parah Aduma's ashes etc., AND also influence the Yid to rise to greater heights!
In order for the Kohen to properly 'connect' & be able to have an hashpa'ah on his petitioners. He must be able to lower himself down & 'see' the world from the latter's perspective. He must experience a bit of Tumah himself..... only then can he help other rise out of their Tumah!
And that, my friends, is why GuardYourEyes succeeds even where others have failed!
Rebbeim & good friends can give good advice & encouragement, but they have not been down in the trenches themselves. The devoted pals from this Holy GYE Kehilla understand each other & the struggles we are going through better than anyone. Therefore, we feel a kinship amongst ourselves greater than any friendship in the world!!
