The Anattalakkhana Sutta, the Discourse on the Not-Self Characteristic, is, by traditional accounts, the second discourse delivered by the Buddha, shortly after his first discourse setting the Wheel of the Dhamma in motion. His audience was the same five bhikkhus who had heard that first discourse in which the Buddha set the Wheel of the Dharma in motion. At the conclusion of that first discourse, the Venerable Aññakaṇdañña had attained Enlightenment, had become an arahant. This second discourse awakened the other four; the final line of the sutta summarizes the historical moment: “And there were then six arahants in the world.”
