大乘起信論義記別記 1.49

1.49

Twenty-seventh, within the pure division of pratītyasamutpāda there are four propositions: 1. originally existent, referring to the aspect of tathatā; 2. originally existent produced through cultivation, referring to original enlightenment because it is established in contrast to the initial; 3. produced through cultivation being originally existent, referring to nirvikalpajñāna because it is accomplished through original enlightenment conforming to defilement; 4. produced through cultivation, referring to the wisdom of initial enlightenment, which is originally absent and now existent. These four meanings are the same pratītyasamutpāda; whichever single gate is raised, none fail to fully subsume the rest. Understand it accordingly.
