“Nirodha” is a Sanskrit term meaning the unmaking of sensual craving and conceptual attachment – that is, the cessation of suffering and its causes. The third noble truth expresses the idea that suffering can end by attaining dispassion.
Nirodha extinguishes all forms of clinging and attachment. This means that suffering can be overcome through human activity, simply by removing the cause of suffering.
Attaining and perfecting dispassion is a process of many levels that ultimately results in the state of Nirvana. Nirvana means freedom from all worries, troubles, complexes, fabrications and ideas. Nirvana is not comprehensible for those who have not attained it.
