avidya

This term originates from Sanskrit and is used primarily within the specialized registers of Indian philosophy, theology, and yoga studies. It does not refer to a simple lack of education or intellectual ignorance, but rather to a profound, existential blindness that prevents an individual from perceiving the true nature of the self and the universe.

In a spiritual context, it is viewed as the root cause of suffering and the cycle of rebirth. Because it is a technical term from a non-English source, it is typically treated as an uncountable abstract noun in English discourse, referring to the general state of ignorance rather than a countable instance of it.
