259. “However, if one, etc.” However, if one waits until the Kedusha De-Sidra has been completed, those wicked ones in ‎Gehennom accept upon themselves the judgment of the Holy One, blessed be He, and they fulfill for that person all the blessings that the community recites, namely: “May God give you the dew of the heaven” [Genesis 27:28]; “Blessed shall you be in the city, and ‎blessed shall you be in the field” [Deuteronomy 28:3] etc. ‎

Explanation: By reciting the Kedusha De-Sidra [people] draw forth a great illumination, through which they are ‎spared from the judgment of Gehennom. When the wicked in Gehennom see this, they regret their evil ‎deeds and accept upon themselves the judgment of the Holy One, blessed be He, [namely, they accept] that they deserve their ‎punishments. Because that man [who they saw] led them to accept the judgment upon themselves and to sanctify the ‎name of Heaven, all those blessings that are recited by the community at the end of Shabbat, in the verses beginning with: “May God give you...” ‎are fulfilled with respect to that person. ‎
