Grammatical Analysis
Uddhacca-kukkucca: [nt.] restlessness and remorse; agitation and worry. Formed by uddhacca (restlessness, scattering upward) + kukkucca (remorse, regret over misdeeds, wrong behavior).
Orthodox Definition
Uddhacca-kukkucca is the fourth of the five mental hindrances (nīvaraṇa). Like the previous entry, they are grouped together because they manifest as a single cloud of unworkable, scattering agitation, but represent two distinct mental factors:
- Uddhacca: Restlessness. The intrinsic flitting or scattering of attention away from the object, like ash thrown into the air by wind. Arises in all twelve unwholesome cittas.
- Kukkucca: Remorse/Worry. The specific mental biting or post-facto regret regarding evil deeds done or good deeds left undone. Doctrinally rooted in aversion (dosa).
The commentaries compare restlessness to a town under siege by bandits, where everything is scattered and chaotic. It is remedied by anchoring the mind to a grounding object, cultivating calmness, and studying the discipline (Vinaya) to clear up doubts regarding conduct.
It is temporarily countered by the jhāna factor of spiritual pleasure (sukha) and fully eliminated by Arahatship (for Uddhacca) and Non-Return (for Kukkucca).
