Answer

I think you are asking about Keval Gyan.

Keval Gyan means perfect, complete, and infinite knowledge. In Jain Dharma, it is the highest form of knowledge attained when all ghāti karmas, especially jñānāvaraṇīya karma that obstructs knowledge, are completely destroyed.

Explanation

A soul that attains Keval Gyan becomes a Kevali. Such a soul directly knows all substances and their infinite modes across past, present, and future.

All Tirthankars attain Keval Gyan before giving divine preaching.

Spiritual Understanding

Keval Gyan shows the pure nature of the soul. In its real form, the soul has infinite knowledge, infinite perception, infinite bliss, and infinite energy. These qualities are covered by karma, and through right faith, right knowledge, right conduct, and spiritual purification, the soul progresses toward liberation.

Takeaway

Keval Gyan is the complete awakening of the soul’s infinite knowledge.
