> I have read that the Buddha said the cause of suffering is ignorance > of the "nature of reality". Is this correct? Coming into existence or 'birthing' (jati) is the cause of suffering (dukkha). [Dependent Arising - Paticca samuppāda][1] by [Piya Tan][2] > What is the "nature of reality" that the Buddha talks about? All conditioned things (forms, verbalization, mental thoughts), are forever changing (anicca), lead to suffering (dukka), and devoid of a permanent entity/owner (anattma). Read about the Tilakkhana or the Three Characteristics in the Dhamma. may you be happy.
