Step-by-step explanation:
The term 'Impermanence, no-self, and suffering' refers to the Three Marks of Existence in Buddhism. These are fundamental concepts that reflect the nature of reality according to Buddhist teachings. The first mark, Impermanence, states that all things are constantly changing and nothing is permanent. The second mark, no-self, emphasizes the idea that there is no fixed, unchanging self or soul. The third mark, suffering, acknowledges that suffering is an inherent part of existence and arises from attachment and craving.
