the four noble truths presupposed what three characteristics of reality
Three marks of existence In Buddhism, the three marks of existence are three characteristics (Pali: tilakkhaṇa; Sanskrit: trilakṣaṇa) of all existence and beings, namely impermanence (anicca), unsatisfactoriness or suffering (dukkha),[1] and non-self (anattā).[2][3][4] These three characteristics are mentioned in verses 277, 278 and 279 of the Dhammapada.[5] That humans are subject to delusion about the three marks, that this delusion results in suffering, and that removal of that delusion results in the end of suffering, is a central theme in the Buddhist Four Noble Truths and Noble Eightfold Path.
