Avijjā: Ignorance
Avijjā is the not-knowing sitting underneath every wrong turn. Blindness here runs deeper than the eyes, since these travelers do not know the way, do not know the paths, and do not know that they are lost. Someone feeling along the wall of an unlit room is certain the door is on the left, and that certainty is the blindness, not the dark.
Kalyāṇamitta: The good friend
A kalyāṇamitta is one who walks ahead on a road already known. "I will lead them" and "I will not forsake them" are the two halves of that work: a hand held out at the start of the long road home, and the same hand still there when the ground turns rough. Ānanda once called such friendship half the holy life and was told it is the whole of it.
Magga: The path
Magga is the walkable route out of suffering, set out in eight parts. Walking paths they don't know is the ordinary condition of anyone setting off, since a road can be described in full and still be strange under the feet. Directions to a town you have never visited leave every turn to be made on your own legs, and the walking is what turns the description into knowledge.
Ujupaṭipatti: Straight practice
Ujupaṭipatti is practice that runs straight, recited daily as a mark of those who follow the Buddha. Crooked places show up in conduct long before they show up in landscape: the bent word, the buried motive, the quiet deal made with oneself. Arrow makers heat the shaft and work it straight before it will fly true, and the same patient handling makes a life go where it is aimed.
Vijjā: Clear knowing
Vijjā is the knowing that ends the not-knowing. Making darkness light happens in the seeing: the same stones, the same turns, all of it now plain. Shutters go up at dawn and the shape that loomed all night is a chair with a coat thrown over it.
