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:

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.

"Everything that has a beginning has an end.” means every-thing, every conditioned, manifested thing is impermanent. Nibbana is not conditioned and it is not manifested state, so it does not have a beginning or end

My English is not good so I looked to the meaning of eternal. It says that: "lasting or existing forever; without end"

If you try to describe Nibbana with using "time" then it won't lead you to the right direction because Nibbana is the unconditioned. It is timeless. You can use that term, If you mean being "deathless" by saying eternal. Nibbana is free from any conditioned state. It is free from birth, death, time. It is the unmanifested state.

Thich Nhat Hanh wonderfully talks about Nibbana: https://www.youtube.com/watch?v=odWIPhj-ivo

The pali is the usual “yaṃ kiñci samudayadhammaṃ sabbaṃ taṃ nirodhadhamman”ti, which is the usual, badly said: whatever will samudaya will nirodha. so it is the usual whatever is subject to arising will cease too.

And nibanna does not arise and does not cease, that's the whole point of nibanna.

What we usually understand as happiness is dependent on specific condition, which need to be controlled, arranged, fulfilled and satisfied in order to reach that specific and temporary state.

The happiness of Nibbana is what remains after removing the desire for control and satisfaction of the senses and the ego. If you eliminate the conditions for suffering, what remains is peace without conditions. Thus, you don't need anything in special to feel satisfied, because craving, aversion and ignorance have been eradicated. You feel content because you took off what blocked that peace of simplicity and renunciation.

That's why it's called "The Unconditioned".

As long as the conditions (craving, aversion and delusion) are uprooted, Nibbana should be eternal. If those conditions are still there in the mind, then, at most, you can have "glimpses" of Nibbana.

Also, remember that:
"Sabbe sankhara anicca": everything conditioned is impermanent.

"Sabbe sankhara dukkha": everything conditioned is unsatisfactory.

"Sabbe dhamma anatta": all dhammas are not-self

The word "Dhamma" can be used to talk about the Buddha's teachings, as well to refer to any phenomena. It all depends on the context. And I think the quote you posted is talking about conditioned dhammas, i.e. sankharas.

Kind regards!
