Saṃsāra: Wandering on
Saṃsāra is the endless faring from one birth to the next. Exiles on the Babylon road already know its shape: far from home, moving without arriving, every camp another stretch of the same road. Coming back to Zion is what the end of that wandering feels like from the inside, the road running out because you have finally arrived.
Vimutti: Release
Vimutti is the mind's freedom once its bonds are cut. Ransom is a word from the slave market, where someone else pays and the chain comes off a person who could not remove it alone. Here a hand that is not their own opens the lock, and the long walk home is still done on their own feet.
Sokaparideva: Sorrow and lamentation
Soka is grief and parideva is the wailing that comes out of it, a pair the old teaching always names in one breath. Sorrow and sighing are that same pair: the ache sitting in the chest and the sound the breath makes leaving it. Both are given legs here, and they run because nothing holds them in place any longer.
Nibbāna: The fire going out
Nibbāna is a flame gone out for want of fuel. Sighing is the noise of heat still burning, breath pushed out over and over by something that will not let up, and when the burning stops the breath simply goes quiet. Coolness is the oldest word for this, and people walking out of a desert into their own city would recognize that word before any other.
Pīti: Joy that lifts the body
Pīti is gladness felt physically, the kind that raises the skin and moves the feet. Coming with singing is exactly how it behaves, joy that has to get out through the throat, the way people sing on the last mile of a long walk home. Set on their heads, it rests where a crown rests, worn out in the open where everyone can see it.
Nirāmisa sukha: Ease with no bait in it
Sukha of this kind leans on nothing that can be carried off. Ordinary gladness has a hook hidden in it, since it lasts only as long as you keep the thing that caused it, and Babylon taught these people how fast a good thing is taken. Joy called everlasting draws on a supply that no one owns, which is why it can sit on the head of someone who owns nothing yet.
