Kevala jnana, often translated as absolute or perfect knowledge, occupies a specific place in Jain metaphysics that distinguishes it from enlightenment concepts in neighboring traditions. Jain philosophy holds that every soul, jiva, possesses the capacity for complete knowledge intrinsically, but that this capacity is obscured by karma, understood in Jain thought as a subtle form of matter that adheres to the soul through action, especially action driven by passion or attachment. Ascetic practice, non-violence and detachment are valued specifically because they are believed to halt further accumulation of this karmic matter and burn off what has already accumulated, gradually uncovering the soul's natural omniscience rather than producing something new.
A being who has attained kevala jnana is called a kevalin, and Jain tradition holds that such a being knows all substances in all their states across all of time simultaneously, without needing to reason from one fact to another. Mahavira's kevala jnana is presented not as a private mystical experience but as the objective completion of a process available in principle to any soul willing to undertake sufficiently thorough ascetic discipline, part of why Jain monastic practice remains so demanding compared with many other traditions.
As with other events placed early in Mahavira's traditional biography, the specific circumstances and date rest on scripture and hagiography recorded well after the fact, and historians treat the narrative details, if not the general shape of a renunciant's ascetic path, with appropriate caution.
