Literature Reference: Humbly I receive the wise gaze, with modest virtue I bear the earth's grace. Diligently I follow the queen's command, reverently I uphold the ancient rules. Though I strive to soothe the customs, yet the return to purity remains lacking. Unable to expand the ultimate way, how can I align with the bright spirits?
