仁王經疏 2.298

2.298

釋曰：第二、結上四義。文有四節：一人中行不可得，以生空故。二法中行不可得，以法空故。三境中行不可得，所緣空故。四解中行不可得，能緣空故。

Explanation: Second, concluding the above four meanings. The text has four sections: 1. Practice within persons is unobtainable, because persons are empty. 2. Practice within phenomena is unobtainable, because phenomena are empty. 3. Practice within objects is unobtainable, because the cognitive object is empty. 4. Practice within understanding is unobtainable, because the cognizing subject is empty.
