14.267

第二種類微細，景云：風性無礙，去處無礙，中有亦爾，於十方界求受生處去無障礙，山石直過。

Regarding the second, subtlety of category, Jing says: The nature of wind is unimpeded, and its destination is unimpeded; the intermediate state is also like this: seeking a place of rebirth in the realms of the ten directions, it proceeds without obstruction, passing straight through mountains and rocks.
