The Nirvana taught by Buddha is a state transcending all that is chaotic, noisy and binding, to reach a state of liberation and freedom that is tranquil and peaceful. This state of liberation and freedom marks the consummation of full Enlightenment in Buddhism. Nirvana is rich in content — being liberated from cyclic rebirths, that are rooted in ignorance and delusion, to gain liberation and freedom is based upon wisdom. Nirvana is also described as "uncompounded", "non-arising" (non-abiding, non-extinction). This is because Buddha described all that is worldly as compounded, that is, its basic nature is arising and cessation caused by delusion and intentional actions. Such arising and cessation is characterised by chaos, relativity and bondage. Once one has effected a breakthrough from such conditioned arising and cessation that is characterised by vexation, discrimination and bondage, one attains the state that is ineffable and indescribable, but provisionally called the unconditioned Nirvana with no arising and no extinction.
