how is it that queequeg comes back to life?

Queequeg gets in his coffin with his harpoon, and asks for his little god, Yojo. The delusional Pip wishes to make a game of Queequeg's burial. But just as every preparation for death is made, Queequeg suddenly rallies and returns to health. Queequeg believes that a man could make up his mind to live and sickness could not kill him: nothing but a whale or a violent, ungovernable force could destroy a man in such a condition. Queequeg continues to use his coffin as a sea chest, and carves into the lid the tattoos on his body.
