二、「今約」下，開章別釋，二：初、實疾，二：初、標示分章。二、依章正釋，四：初、辨因果疾相。「瘵礙」者，瘵，側界反，病也。「同篋性異」者，色身如篋，四大如蛇。《光明》云「地水二蛇其性沈下，風火二蛇性輕上升。」「互起增損」者，水增火損則成冷病等，餘大比說。

Second, from "Now regarding" downward, opening the sections for detailed explanation, which has two parts: first, the real illness, in two parts: first, marking, indicating, and dividing the sections; second, directly explaining according to the sections, in four parts: first, distinguishing the marks of cause-and-effect illness.

As for "same box, different natures," the physical body is like a box, and the four great elements are like snakes. The *Golden Light* states: "The two snakes, earth and water, have natures that sink downward; the two snakes, wind and fire, have natures that are light and rise upward." As for "mutually arising in increase and decrease," water increasing and fire decreasing results in cold illnesses and the like; the rest of the great elements are explained by analogy.
