"The Kaddish (Jewish prayer for the dead) is a prayer for peace between nations, between individuals, and peace of mind.
As a Jew, Willow would recite the Kaddish for Tara (her soulmate) three times a day over the past year. On this the first anniversary of Tara's death (Yahrzeit), Willow would say the Kaddish at Tara's grave, and "unveil" Tara's headstone. In so doing, she would release Tara's soul, (which remains earth bound for the year of mourning) to heaven."
