Avidya

Avidya, ignorance, is in Indian thought not merely a lack of information but a positive misapprehension with effects, and it is treated as a cause rather than as a gap. Removing it is therefore not education in the ordinary sense.

In Advaita Vedanta avidya is the root of the entire predicament. It is adhyasa, superimposition, taking what is not the self to be the self, treating the body, the mind and their history as what one is. Shankara opens his commentary on the Brahma Sutras with an analysis of it, using the standard examples of the rope mistaken in dim light for a snake and mother-of-pearl mistaken for silver: the fear is real, the snake is not, and what removes the fear is not action but seeing correctly. Because the error is about what is already the case, its removal is the whole of liberation; nothing needs to be produced or attained, and knowledge rather than action is therefore the means. Later Advaita debated at length whether avidya and maya are the same, whether ignorance has its locus in the individual self or in Brahman, and what its ontological status can be, since if it were real it could not be removed, and if wholly unreal it could not bind. The school's answer, that it is anirvacaniya, not describable as either, was a standing target for its opponents.

In Buddhism, avijja heads the twelve links of dependent origination and is the last of the fetters to be broken. What is not known is the four noble truths and the three marks of existence, and specifically the taking of impermanent, non-self processes for a permanent self.

In Yoga, avidya is the first of the five klesas or afflictions, and Patanjali defines it exactly: taking the impermanent for the permanent, the impure for the pure, the painful for the pleasurable, and the not-self for the self (Yoga Sutra 2.5). The remaining four afflictions, egoism, attraction, aversion and clinging to life, are presented as growing out of it.

The traditions differ over what ignorance is ignorance of, and that difference is the difference between them. For Advaita it conceals a real self that is identical with Brahman; for Buddhism it fabricates a self that was never there at all. This opposition is among the oldest and sharpest in Indian philosophy, and each side developed extensive polemic against the other's account, Vedantins arguing that a doctrine of no-self cannot explain who is bound or liberated, and Buddhists arguing that a permanent self cannot explain change or the possibility of release.

The question the main entry raises but does not resolve, whether avidya belongs to the individual self or to Brahman, became the point of division between the two major interpretive schools of later Advaita, the Vivarana and Bhamati traditions, named for their foundational commentaries on Shankara's work.

The Bhamati school, following Vachaspati Mishra's tenth-century commentary, held that avidya has its locus in the individual self (jiva), since it is the individual, not Brahman, who experiences bondage; on this reading each jiva carries its own avidya, and Brahman is the object the ignorance obscures rather than the site where it resides, a position that preserves Brahman's purity but faces the difficulty of explaining how the jiva, itself a product of avidya, can be avidya's locus without circularity. The Vivarana school, following Prakashatman's commentary, held instead that avidya has its locus in Brahman itself, since only Brahman, as the one real consciousness, is available to serve as a substrate for anything, with the jiva understood as a product of Brahman conditioned by this Brahman-based ignorance rather than a pre-existing bearer of its own.

Each position generated difficulties: the Bhamati view struggled to explain the origin of individual selves prior to any ignorance-generated individuality, while the Vivarana view drew the objection that locating ignorance in Brahman risks compromising the purity Advaita is committed to as Brahman's defining nature. Later manuals typically present both without adjudicating, treating the dispute as evidence that Advaita's founding insight was compatible with more than one account of the mechanics behind it.
