Nirvana (Pali: Nibbana) is the ultimate spiritual goal in Buddhism. It signifies the cessation of suffering (dukkha) and the cycle of rebirth (samsara). This is achieved by extinguishing the "three poisons" or "three fires": craving (tanha, desire), aversion (hatred), and ignorance (delusion). Therefore, the extinction of desire, which is seen as a primary cause of suffering and attachment, is a central aspect of achieving Nirvana.
