維摩經玄疏 2.82

2.82

Other-arising: the sūtra states, "Mind does not arise alone; it necessarily relies on conditions to arise." Therefore the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra says, "When there is a condition, thought arises; without a condition, thought does not arise." One should know that all phenomena arise from external conditions.
