觀心論疏 1.35

1.35

偈云：「諸道各有法，了不自尋研，忽窺窬釋教，動經十數年。非但彼法拙，必有謀壞心，此則迦毘梨，仙聖豈聽然。為是因緣故，須造觀心論。」此兩偈半明外道之得失也。然外道窺窬釋教，不出二意：一者賤其法拙；二者謀壞佛法。窺窬覓過事，非好心而尋佛教也。昔外道難破一切法師，唯無奈一禪師何。其母勸云：「汝若將禪師論者，罵『驢馬頭，一切諸獸之頭。』即可得勝。」外道遂隨其母計得勝，後受迦毘梨之身，一身而有千頭。既運惡心，冥聖豈聽也！事如偈說。

The verse says:
"The various paths each have their methods,
Yet they do not investigate them themselves;
Suddenly peeping into the Śākya teachings,
Over a period of ten or more years.
Not only is their own method clumsy,
They must have a mind conspiring to destroy it.
This is Kapila;
How could the ṛṣis and sages permit it?
For these reasons,
One must compose the Treatise on Contemplating the Mind."
These two and a half verses clarify the gains and losses of non-Buddhists. Now, when non-Buddhists peep into the Śākya teachings, it amounts to no more than two motives: first, they disdain their own clumsy methods; second, they conspire to destroy the Buddha-Dharma. Peeping to seek faults is not an inquiry into the Buddhist teaching with a good heart. Long ago, a non-Buddhist refuted and defeated all dharma masters, but could do nothing against a single dhyāna master. His mother advised him, saying: "If you debate with the dhyāna master, revile him by saying, 'Head of a donkey, head of a horse, heads of all beasts!' and you will gain victory." The non-Buddhist then followed his mother's plan and attained victory; later he received the body of Kapila, with a thousand heads on a single body. Since he harbored an evil mind, how could the unseen holy ones permit it? The matter is as the verse explains.
