“Mendicants, I will teach you the unconditioned and the path that leads to the unconditioned.
*Asaṅkhatañca" vo, bhikkhave, desessāmi asaṅkhatagāmiñca maggaṁ.

That is not the passage, this is the passage

Sn43.14

1.1the constant … 1.2

“Monks, I will also teach you permanence and the path leading to permanence …

The important keyword here is Dhuvañca which means constant/permanent/changeless

Even if you use suttacentral dictionary it can mean permanent and there’s no difference between constant and permanent it’s just synonym

@sujato

still the terms ‘stability’ and ‘lawfulness’ are virtually the opposite of ‘impermanence

As we see that the terms “stability” is virtually the opposite of impermanence furthermore we can say that the opposite of “constant” is impermanence or inconstant this shows how genius Ven sujato is
