[676] What is sharp wisdom (tikkhapaññā), in the phrase "they lead to the state of sharp wisdom"?
It is sharp wisdom because it swiftly breaks the defilements (kilesa). It is sharp wisdom because it does not tolerate an arisen thought of sensual pleasures (kāmavitakka), but abandons it, dispels it, makes an end of it, and brings it to non-existence. It is sharp wisdom because it does not tolerate an arisen thought of ill will (byāpādavitakka), but abandons it, dispels it, makes an end of it, and brings it to non-existence. It is sharp wisdom because it does not tolerate an arisen thought of cruelty (vihiṃsāvitakka) … it does not tolerate evil, unwholesome dhammas whenever they arise, but abandons them, dispels them, makes an end of them, and brings them to non-existence. It is sharp wisdom because it does not tolerate arisen lust (rāga), but abandons it, dispels it, makes an end of it, and brings it to non-existence. It is sharp wisdom because [it does not tolerate] arisen hatred … arisen delusion, arisen anger (kodha), grudge (upanāha), denigration (makkha), domineering (paḷāsa), envy (issā), avarice (macchariya), deceit (māyā), hypocrisy (sāṭheyya), obstinacy (thambha), contentiousness (sārambha), conceit (māna), excessive conceit (atimāna), vanity (mada), heedlessness (pamāda), all defilements, all misconduct, all volitional formations (abhisaṅkhāra) … all kamma leading to existence (bhavagāmikamma) — it does not tolerate them, but abandons them, dispels them, makes an end of them, and brings them to non-existence. It is sharp wisdom because in a single sitting the four noble paths, the four fruits of the ascetic life (sāmaññaphala), the four analytical knowledges (paṭisambhidā), and the six direct knowledges (abhiññā) are attained, realized, and touched by wisdom. This is the sharp wisdom in the phrase "they lead to the state of sharp wisdom."
