Saddhā: Confidence
Confidence is trust extended toward what has not yet been verified for oneself. Promises granted work like a deed signed over long before the house is ever entered, so the weight of "precious and exceedingly great" rests entirely on who signed it. Peter, writing with his own death close at hand, passes along something he cannot display, and asks that it be leaned on in the meantime.
Taṇhā: Craving
Craving is the thirst that pulls toward whatever pleases. "Lust" here reaches wider than one forbidden appetite: it is the steady grasping that turns the world into a supply of things to be gotten, food, standing, safety, praise. Corruption comes in by it, so the rot starts in the grasping hand and only afterward shows up in the thing grasped.
Āsava: Taints
Taints are the seepage that keeps a mind fermenting. Corruption of this kind is decay already under way, the way milk left out on the counter goes sour long before anyone notices the smell. It sits in the world as a standing condition, which is why appetite for pleasure, the wish to keep on existing, and unclear seeing are counted as things that leak slowly and stain whatever they touch.
Nissaraṇa: Escape
Escape is the exit that exists from any given bind. "Having escaped" stands in the past tense, a door already shut behind the reader, handed over as finished business before it has been felt as such. For everything that binds there is a way out, and a person standing in the open air needs no argument that the room was stifling.
Brahmabhūta: Become Divine
Brahmabhūta, "become divine," is what the early texts call one whose training is complete. Partaking in such a nature works like adoption: a name and an inheritance arrive that were never earned, and the family likeness comes along afterward. Escaping and partaking land in a single breath here, because a heart with nothing seeping out of it has already taken the shape being promised.
