大乘起信論裂網疏 4.41

4.41

The nature of fire within wood illustrates the untainted seeds within the ālaya. "If no one knows of it" illustrates not encountering the condition of a kalyāṇamitra. "Does not apply effort" illustrates not cultivating superior practices. Fire emerging illustrates generating wisdom. Burning the wood illustrates severing afflictions and destroying the consciousness of combination. The application of the metaphor can be understood.
