This prayer, the mourner's kaddish, is recited by those in mourning (up to a year) following the death of a family member (or others in more reform congregations). It is also recited upon the anniversary of their passing. As you can see it makes no reference to death or mourning, but rather praises G-d for his omnipotence, accepts the righteousness of his judgement, and asks his blessings upon us all.
