In clarity is born for him the cessation of all affliction; for soon for the one of serene mind, wisdom is firmly established

The consequence of prasāda: sarva-duḥkhānāṃ hāniḥ (destruction of all pains). It is not anesthesia but understanding that dissolves suffering at its root.

Prasanna-cetasaḥ (for the one of serene/joyful mind). Serenity precedes wisdom; it does not follow it. First emotional pacification, then intellectual clarity.

Āśu (soon) — it is not a long process once conditions are given. Paryavatiṣṭhate (is firmly established) — buddhi settles in truth.
