Grammatical Analysis
Avijjā: [f.] ignorance; nescience; blindness. Formed by negative prefix a (not) + vijjā (true spiritual knowledge, clear vision). From root vid (to know, perceive). Literally means the active lack of correct spiritual vision.
Orthodox Definition
Avijjā is the absolute structural cornerstone of unwholesome reality. It is the first link in the twelve-fold chain of Dependent Origination (avijjā-paccayā saṅkhārā) and is doctrinally identical to the unwholesome mental factor of delusion (moha-cetasika).
The orthodox tradition defines avijjā not as mere general ignorance of worldly facts or academic data, but specifically as non-knowledge regarding four structural axes:
- Non-knowledge of suffering (dukkha).
- Non-knowledge of its origin (samudaya).
- Non-knowledge of its cessation (nirodha).
- Non-knowledge of the path (magga).
The commentaries explain that avijjā acts like a thick psychological cataract, masking the true characteristics of impermanence, suffering, and non-self, while projecting false illusions of permanence, pleasure, and substantial identity. It is the ultimate root of all karmic drifting in saṃsāra.

A person whose eyes are overcome by a cataract does not see forms at all, or if they see anything, they see it incorrectly; similarly, a foolish person overcome by avijjā does not understand or see suffering and so forth, or understands it incorrectly; thus, avijjā is like a cataract. Saṅkhāras are like the parts of a silkworm’s cocoon, because they are made by oneself (the foolish person) and are the cause of one’s own wandering in the round of existence. Viññāṇa not gaining a foothold without the appropriation of saṅkhāras is like a prince not gaining a foothold without the appropriation of a guide; here, the commonality is not gaining a foothold without appropriation.— Vibhaṅga-mūlaṭīkā (pa)
