35.6.4

三觀詣理之妙門。 今明此義。 故借為喻也。 仰佛法遐蹤。 神功浩曠。 求茲非遠。 寄以一心。 體之有原。 總乎三智。 若其假方便以致殊。 會歸一道。 寂然而雙照。 三觀之名。 出自瓔珞。 經。 云從假入空。 名二諦觀。 從空入假。 名平等觀。 雙照二諦。 心心寂滅。 自然流入薩婆若海也。

The three contemplations are the wondrous gate that penetrates to principle. Now in clarifying this meaning, we borrow these as metaphors. Looking up to the distant traces of the Buddha's Dharma, its spiritual efficacy is vast and expansive. Seeking this is not far off; it is entrusted to the one mind. Grasping its origin, it synthesizes the three wisdoms. If one employs provisional skillful means to bring about distinctions, they converge back to the one path, tranquil and doubly illuminating. The names of the three contemplations come from the Yingluo jing. The sūtra says: "Entering emptiness from the provisional is called the contemplation of the two truths. Entering the provisional from emptiness is called the contemplation of equality. Doubly illuminating the two truths, mind after mind is tranquil and ceased, naturally flowing into the ocean of sarvajñā."
