When the stains from old habits are exhausted the original light appears, blazing through your skull, not admitting any other matters. Vast and spacious, like the sky and water merging during autumn, like snow and moon having the same color, this field is without boundary, beyond direction, magnificently one entity without edge or seam. Further, when you turn within and drop off everything, realization occurs. Right at the time of entirely dropping off, deliberation and discussion are one thousand or ten thousand miles away. Still no principle is discernible, so what could there be to point to or explain? People with the bottom of the bucket fallen out immediately find total trust.
