第六解經中，煩惱異名有七句。一、五蓋名龜，五支相似故者，泰云：五蓋有覆藏義，除尾一種，以無用故。

Sixth, explaining that in the sūtras, the different names for afflictions have seven phrases. First, the five hindrances are called a turtle because their five limbs are similar. Tai says: The five hindrances have the sense of concealing and covering; excluding the tail as one [part], because it has no function.
