The Upper Realm has one hundred gates (מאה שערים). Each gate has an opening from which flows a wellspring of blessing to the world. From there our forefather Isaac drew one hundred forms of blessing, from the Hundred Gates, from which blessing and bounty and Divine Emanation come forth to all creations. Therefore… the Tent of Meeting (in the Tabernacle) had one hundred foundation rings (אדנים)… Every foundation ring had an opening to receive [blessing].
