觀無量壽佛經義疏 3.222

3.222

"‘When his life is about to end, the manifold fires of hell arrive all at once.’" The manifold fires of hell refer to the boiling cauldrons, hearth coals, molten copper, iron pellets, and the like. Tiantai states, "The manifestation of the fire chariot is indeed the wheel of fire." These are signs of retribution within the cause, karma within one's own mind. Second, the good friend guides and instructs him.
