why Freemason use Checkered floor?

The Masonic checkerboard embodies life’s dualities—light/dark, spirit/matter—laid on the floor to mirror our material world. Here, the physical isn’t evil, but its illusions can trap us: mistaking the body for the soul, separation for truth.

Yet we’re meant to evolve—to transcend “either/or” thinking, unify the mind, and awaken to higher reality. Break the cycle. Rise beyond limits.
