There is one person who appeared in this world, for the welfare of many beings, for the happiness of many, out of compassion for the world, for the good, welfare, and happiness of gods and humans.
Who is that one person? that is the Tathagata, liberated, fully enlightened. This is that one person.

There is one person, who appears in this world, who is unique, second to none, peerless, peerless, peerless, peerless, peerless, the best among human beings. Who is that one person? That is the Tathagata, liberated, fully enlightened. This is that one person.

(Anguttara Nikaya 1:xiii,1,5)
