The initial insight that shows up as a thought or emotion may have a fair amount of clarity about what this is. But the ego mind, the grasping and judging, is looking for reification of its understanding and replaces the initial clarity. As soon as we step out of just this into something about this, we abandon the very insight that was arising. When you meditate it is your opportunity to witness your karma as it is.
