大方廣佛華嚴經隨疏演義鈔 49.4

49.4

疏「本行經說編草為蓋」等者，《賢愚經》第八說。過去有王名為金剛，夫人有胎，恒有七寶大蓋覆於頭上。及生太子，身紫金色，相好具足，蓋在其上，名蓋事王，七寶自至，王四天下，即是佛身。佛言：「阿難！因過去久遠仙人山有辟支佛涅槃後，有長者起塔，以蓋蓋其上，故獲斯報。」名其事也。

Regarding the commentary's statement that "the Benxing jing relates weaving grass into a parasol," and so forth: This is spoken of in the eighth fascicle of the Xianyu jing. In the past, there was a king named Vajra. When his queen was pregnant, a great parasol of the seven precious substances constantly covered her head. When the prince was born, his body was of purple-golden color and complete with the primary and secondary marks; the parasol remained above him, so he was named King Gaishe (Parasol-deed). The seven precious substances arrived of themselves, and he ruled over the four continents—this was indeed the Buddha's person. The Buddha said: "Ānanda! In the remote past, on Mount Ṛṣi, after a pratyekabuddha entered nirvāṇa, an elder erected a stūpa and covered it with a parasol. It is because of this that he obtained such retribution." This relates the event.
