高僧傳 13.68

13.68

釋曇光，會稽人。隨師止江陵長沙寺。性意嗜五經詩賦，及算數卜筮，無不貫解。年將三十，喟然歎曰：「吾從來所習，皆是俗事。佛法深理，未染一毫，豈剪落所宜耶？」乃屏舊業，聽諸經論。識悟過人，一聞便達。

Shi Tanguang was a native of Kuaiji. Following his master, he stayed at the Changsha Temple in Jiangling. He naturally took pleasure in the Five Classics, poetry, rhapsodies, mathematics, and divination, mastering all of them without exception. Approaching the age of thirty, he sighed with emotion and said: 'All I have studied hitherto are worldly affairs. I have not been tinged by a hairsbreadth of the profound principles of the Buddhadharma; how can this be suitable for someone whose hair has been shaven?' He then cast aside his former occupations and listened to the various sūtras and treatises. His understanding surpassed that of others; hearing a thing once, he immediately grasped it.
