Nisga'a worshipped the creator bye standing with their arms stretched up toward the rising sun. They chanted, "K'amligihahlhaahl". K'amligihahlhaahl was a pure spritit that no one could ever see.

At special ceremonies, Nisga'a burned a small portion of food as thanks to K'amligihahlhaahl, before anyone ate anything. These offerings were burned outside on a special fire. Only valuable and sacred articles such as eagle down, red ochre, red cedar bark, copper, elk skins, fishing lines and fat or grease were offered as gifts. The act of burnt offerings was called milgwooks. The smoke carried the milgwooks up into the sky.

Nisga'a did not often ask K'amligihahlhaahl for help. They might ask for help if their lives were put in danger by a natural disaster such as a volcano, earthquake or floods.

To make certain that K'amligihahlhaahl granted their wish, Nisga'a sometimes fasted and performed purifying rituals. In one ritual the person lay down without eating any food or drinking any water for seven days. During that whole time the person did not move. After the seven days, he washed his whole body, then combed the right side of his hair and painted the right side of his face with red ochre'. Because this fast made a person more "balanced" K'amligihahlhaahl was more likely to listen.

Sometimes, when K'amligihahlhaahl was slow to give help, the Nisga'a shamed him with insults. The most common insult was to call K'amligihahlhaahl the "Great Slave".

'Red ochre is a kind of clay. Red has always been a sacred colour for the Nisga'a
