大方廣佛華嚴經隨疏演義鈔 67.7

67.7

Where the commentary says, 'like two bundles of reeds,' it refers to cause and effect being mutually interdependent. This was already present in the first approach, but there it only concerned vijñāna and nāmarūpa being mutually interdependent; here it applies generally to the twelve links of dependent origination. However, the reason it must be called 'bundles of reeds' is that it also takes their being hollow inside: regarding the characteristics of the twelve links of dependent origination, that they exist is called arising, and that they are empty non-entities is called cessation. Arising and ceasing are conventional aggregations, which are also like bundles of reeds.
