Nibbāna is the Unconditioned Element (asaṅkhata dhātu). The word dhātu, derived from the root dhā (“to hold”), refers to a fundamental nature or element. Unlike conditioned things, Nibbāna is not produced or subject to change; it is the cessation of all conditioned phenomena and the end of suffering.
Hello, Bhante. If I understood correctly, my understanding: the aggregates also cease in the Theravada Abhidhamma. Essentially, Nibbana is a dhamma in its own right, functioning as the condition through which those aggregates cease to arise. It isn’t a mental entity—it is not citta—, it is not sentient in anyway, but rather its own separate category of dhamma.
See “What the Nikayas Say and do not Say about Nibbāna” by Bhikkhu Brahmali
This is an authoritative work on the topic and its conclusions are generally in line with the Classical Theravada position.
The abstract from the paper:
“Abstract
The only way of moving towards consensus on the controversial subject of the nature of Nibbāna is by appealing to the sole source of authority common to practically all Buddhists: the Nikāyas/Āgamas. In the present paper I will first give an overview of the usage of the term Nibbāna in the Nikāyas. I will then argue that, according to the Nikāyas, Nibbāna cannot be regarded as a self. Next, I will point out that the Nikāyas do not see Nibbāna as a form of consciousness, including such exceptional kinds of consciousness as anidassana viññāṇa and appatiṭṭhita viññāṇa. Nor can Nibbāna be regarded as equivalent to mind, or any particular state of mind. In the final section I aim to show that the most reasonable interpretation of the Nikāyas is that final Nibbāna is no more than the cessation of the five khandhas.”
Also see “On the Nature of Nibbana” by Mahasi Sayadaw. This is a Classical Theravadin work.
A small selection:
“In nibbāna there are no such things as mind or mental concomitants, which can be met with in the sense-sphere or form-sphere. It naturally follows that mind and matter that belong to the thirty-one planes of existence are totally absent in nibbāna. However, some would like to propose that after the parinibbāna of the Buddha and the Arahants, they acquire a special kind of mind and matter in nibbāna. Such an extraordinary way of thinking may appeal to those who cannot do away with self or ego.
With regard to this proposition a learned Sayādaw reasoned that if there is a special kind of mind and matter in nibbāna, there must also be a special kind of rebirth which gives rise to a special kind of old age, disease, and death, which in turn bring about a special kind of sorrow, lamentation, suffering, distress, and despair. When the teachings explicitly say cessation, it will be improper to go beyond it and formulate an idea of a special kind of existence. Extinction points to nothing other than Nothingness. Nibbāna, which is not involved in mind and matter, cannot be made to get involved either in this world or in other worlds.

Nibbāna is Real
Since nibbāna means the cessation of mind, matter, and mental formations, suggestions have often been put forward that it signifies nothing and is thus useless. However, nibbānais absolute reality, the reality of the nullification of the activities of mind, matter, and mental formations to which the knowledge of the Path, Fruition, and reviewing (paccavekkhaṇa) is inclined. It is the mind-object to which this knowledge is directed. Buddhas, Arahants, and Noble Ones vouch for the truth of its reality. For the sake of argument, let us say that there is no nibbāna where all the cycles of defilement, actions, and results cease. Then no one in this Universe can find peace. In the absence of nibbāna, defilement will play havoc with our lives to produce action, which will bring about results, which will create conditions for the arising of a new group of aggregates attended by suffering. It is only the Path and its Fruition that can exterminate defilements, and this extermination will bring the cycle of suffering to an end. This cessation of suffering is real. Buddhas and Arahants actually reach this stage, and after their parinibbāna all sufferings come to an end.”
