The prayer that praises God and looks forward to God's sovereignty. It is not a prayer for the dead but an affirmation of life. There are longer and shorter forms of the kaddish which is written in Aramaic and is said as a prayer of thanks for life, prayer and Torah.
Kaddish is from the root meaning holy. The prayer is sanctification of G-d and His Name. When Job lost his family and all he possessed he "sanctified the Name of YHWH" instead of getting himself in trouble. The Kaddish is said in mourning the death of a loved one.
(Hebrew): The word means sanctification and is commonly used to refer to a short prayer recited during the period of mourning for a close relative, as well as on the anniversary of the death. The prayer addresses the majesty and power of God and God's name in the universe.
(KAH-dish) Aramaic for â€œsanctification,â€ a prayer recited several times (in multiple forms) during Jewish worship but especially noted for its recitation towards the end of worship, honoring the memory of those who have died. The Kaddish prayer contains no mention of death or grieving; it is a glorious hymn of praise and adoration of God and the divine presence in life.
(pl. Kaddishim): The Kaddish is a prayer sanctifying G-d's Name which is used to signal passage from one stage to another of the liturgy. Kaf: Kaf is the 11th letter of the Hebrew alphabet.

Kaddish is a poem by Beat writer Allen Ginsberg about the death of his mother Naomi in 1956. It was begun in the Beat Hotel in Paris in December 1957, completed in New York in 1959, and published by City Lights Books in 1961 as the lead in the collection Kaddish and Other Poems 1958-1960. It is often considered one of Ginsberg's finest poems, and some scholars hold that it is his best.
"Kaddish" is the fifteenth episode of the fourth season of The X-Files.
