1At Sāvatthī. Then the Venerable Radha approached the Blessed One, sn.iii.80 paid homage to him, sat down to one side, and said to him:[n.98] This sutta is identical with SN18.21 (and SN22.91), the next with SN18.22 (and SN22.92). A whole saṁyutta (SN 23) consists of suttas spoken to the Venerable Radha.

"Venerable sir, how should one know, how should one see so that, in regard to this body with consciousness and in regard to all external signs, I-making, mine-making, and the underlying tendency to conceit no longer occur within?"

"Any kind of form whatsoever, Radha, whether past, future, or present, internal or external, gross or subtle, inferior or superior, far or near— one sees all form as it really is with correct wisdom thus: ‘This is not mine, this I am not, this is not my self.’

"Any kind of feeling whatsoever …
Any kind of perception whatsoever …
Any kind of volitional formations whatsoever …
Any kind of consciousness whatsoever, whether past, future, or present, internal or external, gross or subtle, inferior or superior, far or near— one sees all consciousness as it really is with correct wisdom thus: ‘This is not mine, this I am not, this is not my self.’

"When one knows and sees thus, Radha, then in regard to this body with consciousness and in regard to all external signs, I-making, mine-making, and the underlying tendency to conceit no longer occur within."

Then the Venerable Radha, having delighted and rejoiced in the Blessed One's words, rose from his seat, and, after paying homage to the Blessed One, keeping him on his right, he departed.

Then, dwelling alone, withdrawn, diligent, ardent, and resolute, the Venerable Radha, by realizing it for himself with direct knowledge, in this very life entered and dwelt in that unsurpassed goal of the holy life for the sake of which clansmen rightly go forth from the household life into homelessness.

He directly knew: "Destroyed is birth, the holy life has been lived, what had to be done has been done, there is no more for this state of being." And that bhikkhu became one of the arahants.
