May his great name be blessed, forever and ever.
Blessed, praised, glorified, exalted, extolled, honored elevated and lauded be the Name of the holy one, Blessed is he- above and beyond any blessings and hymns, Praises and consolations which are uttered in the world; and say Amen. May there be abundant peace from Heaven, and life, upon us and upon all Israel; and say, Amen.
He who makes peace in his high holy places, may he bring peace upon us, and upon all Israel; and say Amen.
Having read the translation of the Kaddish Prayer, one should realize that, although Jewish Law requires that the Kaddish be recited during the first eleven months following the death of a loved one by prescribed mourners, and on each anniversary of the death (the "Yahrtzeit"), and by custom in the State of Israel by all Jews on the Tenth of Tevet ("Yom HaKaddish HaKlali'), there is no reference, no word even, about death in the prayer!
The theme of Kaddish is, rather, the Greatness of G-d, Who conducts the entire universe, and especially his most favored creature, each individual human being, with careful supervision. In this prayer, we also pray for peace - from apparently the only One Who can guarantee it - peace between nations, peace between individuals, and peace of mind.
Paradoxically, this is, in fact, the only true comfort in the case of the loss of a loved one. That is, to be able to view the passing of the beloved individual from the perspective that that person's soul was gathered in, so to speak, by the One Who had provided it in the first place.
As Beruriah, the great wife of Rabbi Meir, consoled her husband, upon the death of their two sons, with words to this effect, "A soul is comparable to an object which was given to us - to each individual, to his or her parents and loved ones, to guard and watch over for a limited time. When the time comes for the object to be returned to its rightful owner, should we not be willing to return it? With regard to our sons, let us therefore consider the matter as 'The L-rd gave, and the L-rd took back, may the Name of the L-rd be Blessed!' "
