How many Noble Truths are there?
Prajñā (Sanskrit) or paññā (Pāli) means wisdom that is based on a realization of dependent origination, The Four Noble Truths and the three marks of existence. Prajñā is the wisdom that is able to extinguish afflictions and bring about bodhi. It is spoken of as the principal means of attaining nirvāṇa, through its revelation of the true nature of all things as dukkha (unsatisfactoriness), anicca (impermanence) and anatta (not-self). Prajñā is also listed as the sixth of the six pāramitās of the Mahayana.
