[747] **Should refrain from remorse (kukkucca), should not be negligent** — **Remorse**: fidgeting of the hands is remorse; fidgeting of the feet is remorse; fidgeting of the hands and feet is remorse; perceiving what is allowable as not allowable, perceiving what is not allowable as allowable, perceiving what is blameless as blameworthy, perceiving what is blameworthy as blameless — remorse of such a kind, the being remorseful, the state of remorsefulness, regret of mind (citta), mental perplexity: this is called remorse.
Moreover, remorse — regret of mind, mental perplexity — arises from two causes: from what has been done and from what has been left undone. How does remorse, regret of mind, mental perplexity arise from what has been done and from what has been left undone? "I have done misconduct by body; I have not done good conduct by body" — thus arises remorse, regret of mind, mental perplexity. "I have done misconduct by speech; I have done misconduct by mind; I have destroyed life; I have not practiced abstention from the destruction of life" — thus arises remorse … mental perplexity. "I have taken what was not given; I have committed sexual misconduct; I have spoken false speech; I have spoken divisive speech; I have spoken harsh speech; I have engaged in frivolous talk; I have been covetous; I have harbored ill will (byāpāda); I have held wrong view; I have not held right view" — thus arises remorse, regret of mind, mental perplexity. Thus from what has been done and from what has been left undone there arises remorse, regret of mind, mental perplexity.
Or else, [thinking:] "I am one who has not fulfilled the virtues," "I am one whose sense doors are unguarded as to the faculties," "I am one who knows no moderation in eating," "I am one not devoted to wakefulness," "I am one not endowed with mindfulness and clear comprehension," "I have not developed the four establishments of mindfulness (satipaṭṭhāna)," "I have not developed the four right strivings," "I have not developed the four bases of spiritual power," "I have not developed the five faculties," "I have not developed the five powers," "I have not developed the seven factors of awakening (bojjhaṅga)," "I have not developed the noble eightfold path," "I have not fully understood suffering (dukkha)," "I have not abandoned the origin," "I have not developed the path," "I have not realized cessation" — thus arises remorse, regret of mind, mental perplexity.
**Should refrain from remorse**: one should hold aloof from remorse, refrain from it, abstain from it; one should abandon remorse, dispel it, make an end of it, bring it to nonexistence; being aloof from remorse, refraining from it, abstaining from it, gone out from it, given it up, released from it, detached from it, one should dwell with a mind rid of boundaries. Therefore: "should refrain from remorse."
**Should not be negligent**: one should be one who acts with care, who acts persistently, who acts without stopping, whose conduct is unflagging, who does not cast off desire, who does not cast off the burden — one heedful in wholesome states. "When shall I fulfil the aggregate of virtue not yet fulfilled, or assist with wisdom, in this or that respect, the aggregate of virtue already fulfilled?" — whatever desire therein, effort, endeavor, zeal, vigor, non-retreat, mindfulness and clear comprehension, ardor, exertion, resolve, application: [this is] heedfulness in wholesome states. "When shall I [fulfil] the aggregate of concentration (samādhi) not yet fulfilled … the aggregate of wisdom … the aggregate of liberation … the aggregate of the knowledge (ñāṇa) and vision of liberation …; when shall I fully understand the suffering not yet fully understood, or abandon the defilements not yet abandoned, or develop the path not yet developed, or realize the cessation not yet realized?" — whatever desire therein, effort, endeavor, zeal, vigor, non-retreat, mindfulness and clear comprehension, ardor, exertion, resolve, application: [this is] heedfulness in wholesome states. Therefore: "should refrain from remorse, should not be negligent."
