Citta: Heart-mind
Citta covers thought, will, and mood together, so the heart known in heaven is the whole working mind, wider than feeling. The man who becomes aware of the plague of his own heart is watching that whole apparatus, his aims as much as his grief. Two men kneeling in the same courtyard with the same words carry different minds, and the mind is what gets read.
Cetopariyañāṇa: Knowing another's mind
A rare attainment, hard-won even after long practice. "You, even you only" draws the same line: reading hearts belongs to one who sees, and the people in that courtyard cannot do it to each other. Which leaves each of them the modest work of watching one mind, their own.
Cetanā: Intention
Cetanā is the willing that starts a deed. "All his ways" gets weighed at that root, since the same walk up to the temple can be a bribe, a bargain, or a turning. Someone can lay down a flawless sacrifice with a hard mind and go home carrying exactly what they brought.
Kamma: Action and its fruit
Kamma is deed ripening into result. "Give to every man according to all his ways" describes something already in motion; Solomon asks heaven to do what deeds are doing anyway. A person reaps what was planted, and the harvest is sized by the seed rather than by the volume of the prayer.
Hiri: Conscience
Hiri is the inward recoil from doing what is beneath you. Since no neighbor in that courtyard can see inside a heart, the only witness standing beside a man in the dark is his own mind, and hiri is that witness awake. It restrains where nobody is watching, and that unwatched place is just where heaven's knowing reaches.
Paṭikamma: Making amends
Seeing a fault as a fault, repairing what can be repaired, then holding to restraint going forward: that is how a person grows. Solomon's petitioner has already begun it, knowing the plague of his own heart and spreading his hands toward the house before any pardon arrives. Forgiveness meets a fault brought into the open, while a fault kept hidden goes on working.
