Discrete Infinities

If matter flies through the invincible and limitless abyss,
Of structure aggregate or desolate, its part-less parts
Reforming through the whole,
Then surely where each volatile member dies,
A new form will arise to take its place, in which the former lies,
Immortal matter passing through unending mortal lives:

Not so – a part is not the whole, and when the structure perishes
Though every piece of it survives, the thing it was cannot reply
The errant waves that let it be;
Eternity passes in a thousand deaths,
Since every irreparable type is lost, and my particularity
Is just a tiny, breaking cross.
