Ekantar (often written as Ekānta) can have two Jain-specific meanings, depending on the context:

• One-sidedness (wrong belief or absolutism)

- In Jain philosophy, ekānta refers to taking only one aspect of reality and treating it as the whole truth. This is considered a mithyādarśana (false belief) and is opposed by the core Jain principle of many-sided truth (anekāntavāda). It warns against dogmatic thinking and urges considering multiple viewpoints. This concept is discussed in Jain logic and texts that explain the contrast between ekānta and anekāntavāda. In short: ekānta = one-sided view.

• Single-mindedness in practice or devotion (one-pointed focus)

- In common Jain practice, ekānta can also describe a focused, single-pointed dedication—such as one-pointed attention in tapas, prayer, or devotion to the Tirthankaras. This usage emphasizes steadiness and concentration in spiritual discipline rather than philosophical dogmatism.

Important related ideas:

• Anekāntavāda: the many‑sided nature of truth. This is the central Jain method for approaching reality, encouraging respect for multiple viewpoints rather than a single, absolute stance. Ekānta is what anekānta warns against.
• Digambar vs. Śvetāmbara nuances: both traditions teach anekāntavāda, but discussions about ekānta as a philosophical stance vs. a devotional stance can appear with slightly different emphasis in commentary and practice across traditions. The essential aim in both is to avoid absolutism and cultivate a balanced understanding.
