阿彌陀經通贊疏 1.62

1.62

迦旃延者，梵云摩訶迦多衍那，云迦旃延亦訛也。《大般若》云大迦多衍那，此云大剪剃種男，剪剃種是婆羅門姓。上古有仙，山中靜處年歲既久，鬢髮稍長無人為剃，婆羅門法斥剃髮。一仙有子，兄弟二人俱來覲父。小者乃為諸仙剃髮，諸仙願護，後成仙道，爾來此種皆稱剪剃種。尊者身是男子，威德特尊，揀餘卑姓故云大剪剃種男。又西方亦有取母姓者，今顯是父姓，故置男名。古云扇繩，母戀此子如繩繫扇。又往昔曾為五戒掃地，果招端正無比，遊行化導遇鉢戍多王，怪其端正因問世尊。世尊具答王：「曾助五戒，除穢亦得端正。」王即歡喜更發勝心。辨捷無雙，論義第一也。此尊者辯潟波濤，貌揚氷玉，能將慧炬破長夜之昏朦，迫淬詞鋒挫六師之宗黨，故云辨才也。

As for Kātyāyana, in Sanskrit it is Mahākātyāyana; saying "Jiazhiyan" is also an error. The *Great Prajñāpāramitā* calls him Great Kātyāyana, which means in Chinese "Son of the Great Tonsure Clan." The Tonsure Clan is a Brahmin clan name. In high antiquity, there was an immortal in a quiet mountain retreat; after a long time, his hair and beard grew long and there was no one to shave them, while Brahmin custom disdained shaving hair. One immortal had sons, two brothers, who both came to visit their father. The younger one shaved the hair for the immortals. The immortals vowed to protect him, and later he attained the way of an immortal; from then on, this clan was called the Tonsure Clan. The Venerable One was a male and his majestic virtue was exceptionally revered; to distinguish him from other inferior clans, he is called "Son of the Great Tonsure Clan." Also, in the Western Regions some take their mother's clan; here it is shown to be the father's clan, hence the word "son" is appended. Formerly it was said to mean "fan-cord," as the mother loved this son as a cord ties a fan. Furthermore, in the past he swept the ground for [a practitioner of] the five precepts, and as a result obtained peerless beauty. While traveling to transform and guide, he met King Paśuta, who was astonished by his handsome appearance and asked the World-Honoured One about it. The World-Honoured One answered the king in full: "In the past he helped [one observing] the five precepts and removed defilements; thus he obtained this handsome appearance." The king was delighted and gave rise to an even superior resolve. His eloquence was swift and peerless, foremost in debating doctrine. This Venerable One's eloquence surged like billows, his appearance shone like ice and jade; he could take the torch of wisdom to shatter the dimness of the long night, and wield the sharpened edge of his words to defeat the factions of the six non-Buddhist masters. Hence he is called "eloquence."
