Kṣayak Samkit (also called Kṣāyika Samyak Darshan) is a high, very pure form of Samkit = Samyak Darshan = Right Faith / Right Vision.

In simple words:

• Samkit means: the soul has got right faith in the true Jain tattvas (jīva–ajīva, karma, mokṣa etc.), free from doubt and wrong-belief.
• Kṣayak Samkit means:

- The Mohanīya (deluding) karma of faith is completely destroyed (kṣaya). - Because that karma is fully finished, Right Faith becomes permanent and unshakeable. - After this point, mithyātva (wrong belief) can never return.

So:

• Before this, there can be:

- Aupśamika Samkit – temporary right faith due to just suppression (upśama) of delusion. - Kṣayopśamika Samkit – right faith because some delusion is destroyed and some only suppressed.

• At Kṣayak (Kṣāyika) Samkit:

- Deluding faith‑karma is totally finished. - The soul has a clear, steady, eternal vision of truth. - This is the highest and final stage of Samkit, leading towards Keval‑jñān in upper guṇasthānas.

Digambar / Śvetāmbara

• Both traditions accept these types of Samkit (Aupśamika, Kṣayopśamika, Kṣayika / Kṣayak, sometimes also Vedaka).
• Names or small technical details may differ slightly, but the core idea is the same:

- Kṣayak Samkit = permanent Right Faith caused by complete destruction of faith‑deluding karma.
