The four errors (Skt. catvāro viparyāsāḥ; T. phyin ci log pa bzhi), or four misapprehensions, are mistaking:
- the impermanent to be permanent,
- the painful to be pleasant,
- the dirty to be clean, and
- what has no self to have a self
These four errors are "often described in Buddhist canonical literature as the main underpinnings of sentient beings’ mistaken view of the world."
