Pakra

From Memory Alpha, the free Star Trek reference.

Pakra is a solitary Native American Earth ritual which commemorates dead ancestors.

Chakotay commemorated the anniversary of his father Kolopak's death. Chakotay said a prayer over a pouch of items that may have belonged to his father:

"A-koo-chee-moya. I pray on this day of memories to speak to my father, the one whom the wind called Kolopak. Though I am far from his bones, perhaps there is a spirit in these unnamed skies who will find him and honor him with my song."

Chakotay later adapted this prayer to include Kar, a young Kazon boy who had attempted to kill Chakotay to earn his name. (VOY: "Initiations")
