仁王護國般若波羅蜜多經疏 3.19

3.19

Commentary: When the state's king and great ministers practice it above and transform those below, the four assemblies listen, receive, and all turn toward goodness; this is self-protection. Furthermore, the Suvarṇaprabhāsa Sūtra says: "That king at that time should bathe purely, anoint his body with scent, wear new clean robes, sit on a small lower seat without giving rise to haughtiness, relinquish his independent status, stay free from all arrogance, uprightly rectify his mind and maintain right mindfulness to listen to this king of sūtras, giving rise to the thought of the Great Master toward the Dharma master." Taking that as a standard for this, it makes clear their reverence. From here, the third part explains practicing as taught.
