This is how I heard. At one time the Blessed One was staying in the province of Sāvatthi, in Jeta’s garden, Anāthapiṇḍika’s Monastery. Now on that occasion the Blessed One was meditating where he spent the day. Then the independent brahma Subrahma and the independent brahma Suddhāvāsa went to the Blessed One and stood at opposite doorposts. Then, referring to the monk Kokālika, the independent brahma Subrahma said this verse in the presence of the Blessed One:
“What wise man here would try to measure the Liberated Ones, who have immeasurable qualities? He who would try to measure Liberated Ones with immeasurable qualities must be, I surely think, an ordinary person covered with foolishness.”
