Difficulty
★★☆☆☆ — closing a three-part sequence with its most evocative term
Why this discourse
This discourse closes the sequence begun in SN 17.32 with its most evocative term yet: Devadatta cut off his sukko dhammo, his bright quality, because his mind was overcome and overwhelmed by possessions, honor, and popularity. Where kusalamūla and kusaladhamma name loss in technical, analytical vocabulary, sukka, brightness, carries a more immediately felt image — something luminous, extinguished rather than merely severed.
Reading guide
A more evocative term closing a technical sequence
Sukka, “bright, pure, luminous,” carries connotations the more analytical kusalamūla and kusaladhamma don't — closing the sequence with an image of light going out rather than a purely doctrinal category being severed.
Brightness as a recurring canonical pairing
Kaṇha and sukka, dark and bright, appear as a traditional pair describing unwholesome and wholesome action elsewhere in the canon; invoking sukka alone here implies its opposite by contrast, without needing to name kaṇha explicitly.
Three terms, one deepening image of total loss
Root, then quality, then brightness: each substitution in this three-part sequence moves further from strict doctrinal classification toward something more directly evocative, ending the progression on its most vivid note rather than its most technical one.
Closing without changing the underlying cause
As throughout this three-discourse sequence, the stated cause never varies — overcome and overwhelmed by possessions, honor, and popularity — confirming that all three discourses trace one unchanging cause to three different framings of an identical total loss.
A closed triad preparing a change in register
Having now examined Devadatta's condition through schism and three internal losses, the discourse immediately following this one shifts register entirely, moving from terse statement to full narrative and verse.
Key terms
sukko dhammo — “bright quality” — this sequence's final and most evocative term, closing the three-part progression.
kaṇha … sukka — “dark … bright” — a traditional canonical pairing for unwholesome and wholesome action, implied here by sukka's use alone.
samucchedamagamā — “went to utter severance” — the same term for total loss repeated across all three discourses in this sequence.
abhibhūtassa pariyādiṇṇacittassa — “overcome and overwhelmed” — the unchanged diagnostic cause, identical across the entire sequence.
catutthaṁ — “the fourth” — this discourse's closing numbering tag.
