Is nibbana eternal?

> Arising dhamma is ceasing dhamma so much as ceasing dhamma is arising dhamma as well. What does this mean? The answer should be nibbana is not eternal either. I'm asking about the Pali in this quote from [SN 56.11](https://suttacentral.net/sn56.11/en/sujato) : > And while this discourse was being spoken, the stainless, immaculate vision of the Dhamma arose in Venerable Koṇḍañña: > > *Imasmiñca pana veyyākaraṇasmiṃ bhaññamāne āyasmato koṇḍaññassa virajaṃ vītamalaṃ dhammacakkhuṃ udapādi:* > > “Everything that has a beginning has an end.” > > *“yaṃ kiñci samudayadhammaṃ sabbaṃ taṃ nirodhadhamman”ti.*
