[622] When the Blessed One had attained final Nibbāna (parinibbāna), simultaneously with his final Nibbāna, Brahmā Sahampati spoke this verse: "All beings in the world will lay down the body, since such a Teacher as this, a person without equal in the world, the Tathāgata, attained to power, the Fully Awakened One, has attained final Nibbāna."
