Nirvana is the supreme state free from suffering and individual existence. It is a state Buddhists refer to as "Enlightenment". It is the ultimate goal of all Buddhists. The attainment of nirvana breaks the otherwise endless rebirth cycle of reincarnation. Buddhists also consider nirvana as freedom from all worldly concerns such as greed, hate, and ignorance. No one can describe in words what nirvana is. It can only be experienced directly.
