Therein, Monks, what is the distinction, what is the disparity, what is the difference between The Tathāgata, the Arahant, The Perfectly Enlightened One, and a Monk liberated by wisdom?

The Tathāgata, Monks, the Arahant, The Perfectly Enlightened One, is the originator of the path unarisen before, the producer of the path unproduced before, the declarer of the path undeclared before. He is the knower of the path, the discoverer of the path, the one skilled in the path. And his disciples now reside practicing that path and become possessed of it afterwards.

This, Monks, is the distinction, the disparity, the difference between The Tathāgata, the Arahant, The Perfectly Enlightened One, and a Monk liberated by wisdom.

In this Teaching from Gotama Buddha, he shares the difference between a Buddha and a Practitioner who attains Enlightenment through the guidance of a Teacher.

A Buddha is one who (1) discovers The Teachings through their own independent journey, (2) shares their independently discovered Teachings for the remaining time of their life guiding countless individuals to Enlightenment and (3) leaves The Teachings in such a condition that after their death, countless more individuals will be able to attain Enlightenment.
