Phassa: Contact
Contact is eye meeting form. Standing under the branches she looks, and everything that follows runs out of that one glance, the way a whole afternoon can turn on catching sight of something in a shop window. The looking is innocent; the serpent's work was to keep her eyes on the tree long enough for the rest to build.
Vedanā: Feeling tone
Feeling tone is the pleasant, unpleasant, or neutral flavor arriving with every experience. "A delight to the eyes" is that flavor showing up unbidden, ahead of any decision she makes. Pleasure at the sight of ripe fruit is weather passing through, and the whole question is whether a person stops there or moves.
Ādīnava: The drawback
Ādīnava is the cost sitting inside an attractive thing. Three times she looks at the tree and three times finds something good, food, beauty, wisdom, while the one feature never turned over is the price. A house can look perfect on the walk-through with the rot under the floor, and freedom in front of anything desirable comes from seeing both sides at once.
Taṇhā: Craving
Craving is the thirst for experience. All three of its kinds stand in the branches together: the mouth's wanting in "good for food," the eye's wanting in "a delight," and the deepest, the wish to become other than she is, in "desired to make one wise." Thirst does not ask for fruit, it asks to be someone who has eaten.
Upādāna: Clinging
Clinging is the grasp that holds fuel to a fire. "She took" is the hand doing outwardly what thirst had already done inwardly, fingers closing on the fruit. Wanting can pass on its own; the reach is where a person commits, the way a resolution to quit holds until the hand goes to the pocket.
Kamma: Intentional action
Kamma is intention carried into deed, ripening later. "And ate" is where the whole inward sequence lands in the world and stops being recallable. Then she hands it on and he eats too, because a deed never stays in one pair of hands; it travels the way one person's mood spreads through a room.
