[Advayavada Study Plan – week 16] Dukkha (Pali) or duhkha (Sanskrit) means suffering, sorrow, dissatisfaction, frustration, anxiety, or stress; it is the first of the four noble truths of Buddhism and also the third of the three, in Advayavada Buddhism, four signs or marks or basic facts of being. In Advayavada Buddhism, it furthermore does not include emotional grief nor physical pain, and is, above all, not seen as a permanent feature of reality; it is chiefly understood as the existential distress and distrust of life non-liberated human beings are prone to, and which is essentially caused by the unhealthy and socially infectious feeling that reality does not conform to their desires and mistaken expectations. The unremitting persistency of human distress, alienation and conflict is undeniably due to the very many everywhere not knowing or not understanding or simply disbelieving the true nature of existence.
