33.45

挂旛　若四輩弟子男女命終。造作黃旛懸著剎上。離八難苦得生十方淨土。隨風一轉轉輪王位。乃至吹塵小王之位。其報無量至成菩提（大灌頂十一卷○世有書藥師如來十二誓願者。此是別緣。非經本事）。

Hanging Banners: If male or female disciples among the four assemblies pass away, and one makes yellow banners and suspends them upon poles, they will abandon the sufferings of the eight difficulties and be reborn in the pure lands of the ten directions. With each turn in the wind, one attains the station of a wheel-turning king, and even stirring the dust brings the station of a lesser king; the retribution is immeasurable, extending up to the attainment of bodhi (Twelfth Fascicle of the Da guanding jing; in ordinary society, some write the twelve vows of the Tathāgata Bhaiṣajyaguru upon them, but this is a separate circumstance and not the root matter of the sūtra).
