Let us magnify and let us sanctify the great name of God
in the world which He created according to His will.
May His kingdom come in your lifetime, and in your days,
and in the lifetime of the family of Israel-quickly and speedily may it come. Now respond: Amen May the greatness of His being be blessed from eternity to eternity.
Let us bless and let us extol,
let us tell aloud and let us raise aloft,
let us set on high and let us honour,
let us exalt and let us praise the Holy One-blessed be He!
--though He is far beyond any blessing or song, any honour or any consolation that can be spoken of in this world. Now respond: Amen
May great peace from heaven and the gift of life he granted to us and to all the family of Israel.
Now respond: Amen.
May He who makes peace in the highest bring this peace upon us and upon all Israel. Now respond: Amen.

And while we're at it, Allen Ginsberg on the subject.
