俱舍論疏 17.80

17.80

The passage of the śāstra from "When five operate simultaneously" up to "one obtains two branches, etc." explains the simultaneous operation of five. This also refers to someone setting their mind to receive only two branches: when a wholesome mental consciousness is present, there are five. "Etc." includes receiving three branches when the wholesome five consciousnesses are currently present, and receiving five branches when an unwholesome or indeterminate mind is present.
