The essence (or core) of Kabir's boat was loaded onto it. The wicked remain wicked, oh this old world.

The metaphor of the boat's essence highlights the pure, unwavering truth that Kabir carried. He suggests that while the world is old and flawed, his core message—the essence of truth—is paramount and loaded above all else. It is a sharp observation from the Shayar, criticizing humanity for remaining stuck in its vices and ignorance, despite the availability of divine wisdom.
