4th noble truth

The 4th noble truth is there is a noble eightfold path leading to the cessation of suffering. This is the middle path which is the antidote to suffering. The Path is called Middle because it lies between the two extreme paths of self-indulgence (kàmasukhallikanuyoga) and self-mortification (attakilamathànu-yoga), which had been practised by the Buddha prior to His Enlightenment. The futility of the two paths of practice for the realization of truth led the Buddha to reason out a new path for the purpose of achieving the desired end.
