起信論疏筆削記 5.29

5.29

止觀者，文云：云可修行止觀門？所言止者，謂止一切境界相，隨順奢摩他觀義故。所言觀者，謂分別因緣生滅相，隨順毘鉢舍那觀義故。乃至若止觀不具，則無能入菩提之道。雙明等者，彼文云：若修止者，對治凡夫住著世間，能捨二乘怯弱之見。若修觀者，對治二乘不起大悲狹劣心過，遠離凡夫不修善等。

Regarding "śamatha-vipaśyanā," the text says: "How should one cultivate the gate of śamatha and vipaśyanā? What is called śamatha means stopping all marks of objects, in accordance with the meaning of śamatha contemplation. What is called vipaśyanā means differentiating the marks of the arising and ceasing of causes and conditions, in accordance with the meaning of vipaśyanā contemplation," down to "if śamatha and vipaśyanā are not complete, one will be unable to enter the path of bodhi." Regarding "clarifying both," that text says: "If one cultivates śamatha, it remedies the ordinary person's attachment to dwelling in the world and enables one to abandon the timid and weak views of the two vehicles. If one cultivates vipaśyanā, it remedies the fault of the two vehicles not generating great compassion and having narrow and inferior minds, and keeps one far from the ordinary person's failure to cultivate goodness," and so forth.
