Nirodha (Pali, Sanskrit; Tibetan 'gog pa) — literally refers to the absence or extinction of a given entity. As the third of the Four Noble Truths, it refers specifically to the cessation of Dukkha (Suffering) and its causes; it is commonly used as a synonym for Nirvana.
In the context of the Four Noble Truths, nirodha refers to the cessation of suffering and the causes of Suffering. It is "the cessation of all the unsatisfactory experiences and their causes in such a way that they can no longer occur again. It’s the removal, the final absence, the cessation of those things, their non-arising."
