（二十五　庚午）　長水法師子璿。嘉禾人。初依洪敏師學楞嚴。至動靜之相了然不生有省。聞瑯瑘惠覺道重當世。趨至其門。值其上堂致問曰。清淨本然云何忽生山河大地。覺亢聲云。清淨本然云何忽生山河大地。師豁然大悟。覺謂之曰。汝宗不振久矣。宜勵志扶持以報佛恩。師如教。後住長水。眾幾一千。以賢首宗旨述楞嚴經疏十卷。行於世。

(25. Gengwu) Dharma Master Zixuan of Changshui was a native of Jiahe. Initially, he relied on Master Hongmin to study the Śūraṅgama Sūtra; upon reaching the phrase "the marks of movement and stillness clearly do not arise," he had an awakening. Hearing that Huijue of Langya was deeply esteemed in his generation for his practice of the Way, he hastened to his gate. Encountering him ascending the hall, he posed a question: "If it is pure and fundamentally thus, why do the mountains, rivers, and great earth suddenly arise?" Jue shouted with a loud voice: "If it is pure and fundamentally thus, why do the mountains, rivers, and great earth suddenly arise?" The Master was suddenly greatly awakened. Jue said to him, "Your school has not flourished for a long time. You should exert your will to uphold it, so as to repay the Buddha's grace." The Master followed his instructions. Later, he resided at Changshui, his assembly numbering nearly a thousand. Following the tenets of Xianshou, he composed a ten-fascicle commentary on the Śūraṅgama Sūtra, which was circulated throughout the world.
