1.152

二離辯後一睡眠（二）：初觀察對治、二淨戒對治。論云「自餘修多羅，示現第三從心起睡眠。有二種對治：一觀察對治、二淨戒對治。」或曰：前二睡眠，唯一精進以為能治。今茲一種能治具二，何耶？答：夫障有輕重則治有一多。前二睡眠從食從時，則所治障輕，故以精進通而治之。今從心起者，所治障重，故以觀察淨戒，約法引喻一一別治耳。初觀察對治。

Second, separately distinguishing the latter one kind of sleep (two): first, the antidote of contemplation; second, the antidote of pure precepts. The treatise says: "Other sūtras show the third kind of sleep arising from the mind. There are two kinds of antidotes: first, the antidote of contemplation; second, the antidote of pure precepts." Someone might ask: "For the previous two kinds of sleep, only vigor alone served as the antidote. For this one kind now, the antidote possesses two—why?" Answer: Obstacles have light and heavy, so the antidotes have single and multiple. The previous two kinds of sleep arise from food and from the seasons, so the obstacles to be treated are light, and therefore vigor treats them collectively. That which now arises from the mind has a heavy obstacle to be treated; therefore, through contemplation and pure precepts, each is treated distinctly according to dharma and metaphor. First, the antidote of contemplation.
