James George Frazer,
The Belief in Immortality and the Worship of the Dead…
“ The firebearer now sets the fire on the ground and calls on the ghost to come and take it. They firmly believe that he does so and that having got it he hies away to cast the glowing embers down at the door of the man who has done him to death. They even fancy they see the flickering light carried by the invisible hand retreating through the shadows into the depth of the forest; and in order to follow it with their eyes they will sometimes climb tall trees or launch a canoe and put out to sea, gazing intently at the glimmering ray till it vanishes from their sight in the darkness. ”
