摩訶止觀 2.104

2.104

淮河之北有行大乘空人，無禁捉蛇者，今當說之。其先師於善法作觀，經久不徹；放心向惡法作觀，獲少定心、薄生空解，不識根緣、不達佛意，純將此法一向教他。教他既久，或逢一兩得益者，如蟲食木偶得成字，便以為證，謂是事實，餘為妄語。笑持戒修善者，謂言非道。純教諸人遍造眾惡。盲無眼者不別是非，神根又鈍，煩惱復重，聞其所說，順其欲情，皆信伏隨從。放捨禁戒，無非不造，罪積山岳。遂令百姓忽之如草，國王大臣因滅佛法，毒氣深入于今未改。

North of the Huai River, there are practitioners of Mahāyāna emptiness who handle snakes without restraint; I shall now explain them. Their earlier master practiced contemplation upon wholesome dharmas, but failed to penetrate for a long time; when he let his mind go toward evil dharmas to practice contemplation, he obtained a little concentrated mind and gave rise to a shallow understanding of emptiness. Failing to recognize faculties and conditions, and failing to comprehend the Buddha's intent, he taught this method exclusively to others. Having taught others for a long time, he occasionally met one or two who benefited, like an insect eating wood accidentally forming characters; he immediately took this as proof, calling it true reality and others' [teachings] false speech. Ridiculing those who keep precepts and cultivate the good, he said this was not the Way. He taught everyone exclusively to commit all kinds of evil everywhere. The blind, having no eyes, could not distinguish right from wrong; their spiritual faculties being dull and their afflictions heavy, upon hearing what he said, which accorded with their lustful inclinations, they all believed, submitted, and followed along. Abandoning the prohibitive precepts, there was no wrongdoing they did not commit, and their sins piled up like mountain peaks. Consequently, the common people came to disregard [the Dharma] like weeds, and kings and ministers thereupon destroyed the Buddha-dharma, the venomous influence penetrating deeply and remaining unchanged to this day.
