大方廣佛華嚴經隨疏演義鈔 84.50

84.50

疏「劫賓那」者，疏釋即《音義》中大乘及天台等舊譯為房宿。然有二義：一以父母禱此宿星感此子生故、二云與佛同房宿故。謂初出家時未見佛，始向佛所，夜值雨寄宿陶師房中，以草為座。晚又一比丘寄宿，即推草座與之，自在地坐。中夜相問：「欲何所之？」答云：「覓佛。」後比丘即說法辭去，豁然得道。後比丘即佛也。《增一阿含》云「我佛法中善知星宿日月者，劫賓那第一。」則亦從所知為名。

Regarding the Commentary's mention of 'Kapphina': the Commentary's explanation follows the ancient translations in the Yinyi, the Mahāyāna master, and Tiantai, rendering it as 'Chamber Constellation'. However, there are two meanings: first, his parents prayed to this constellation and were granted this son; second, he stayed in the same room overnight with the Buddha. That is, when he first went forth and had not yet seen the Buddha, he set out toward where the Buddha was; encountering rain at night, he lodged in a potter's room, making grass his seat. Later in the evening another monk lodged there; he yielded the grass seat to him and sat on the ground himself. In the middle of the night they asked each other: 'Where do you wish to go?' He answered: 'To seek the Buddha.' The other monk then expounded the Dharma, took his leave, and [Kapphina] was suddenly enlightened to the Way. That other monk was the Buddha. The Ekottarika-āgama states: 'Among my disciples in the Buddha's Dharma, Kapphina is foremost in having an excellent knowledge of constellations, the sun, and the moon.' Thus he was also named according to his knowledge.
