When form becomes non-dual in its formlessness, even a trace of duality and non-duality disappears.

This beautiful couplet describes a profound spiritual state. It tells us that when our true self, our inherent form, merges with the formless, it becomes one with everything. In this ultimate unity, there's no longer any difference between what has form and what doesn't. Even the ideas of "duality," where things are separate, or "non-duality," where they are one, completely disappear. It's a state beyond all concepts and distinctions, where only pure, unblemished oneness remains, transcending all thought and perception. It's a journey to an absolute state of unity.
