16.281

又解：一切有學練根時，一無間道斷諸根障故，前五無間唯斷果障，第六無間道一時頓斷，果障一品根障九品。

Another explanation: When any person in training refines their faculties, one non-interrupted path severs all the obstacles to the faculties; therefore, the first five non-interrupted paths sever only the obstacles to the fruition, and the sixth non-interrupted path severs all at once: one grade of obstacle to the fruition and nine grades of obstacles to the faculties.
