法華義疏 5.316

5.316

初文又有三：一、明不出為損；二、欲設出方；三、知子宿好。「此舍已為大火所燒」者，三界之舍正為身心二火所燒。「我及諸子若不時出必為所焚」者，上直明燒，今明為火所害，即不出為損也。

The first text also has three parts: first, showing that failing to exit brings harm; second, desiring to devise a method of exit; third, knowing the children's former inclinations. Regarding "This house is already burned by a great fire": the house of the three realms is being burned right now by the two fires of body and mind. Regarding "If I and the children do not exit in time, we will surely be burned by it": the above directly explained the burning; now it shows being harmed by the fire, which means failing to exit brings harm.
