首楞嚴義疏注經 7.111

7.111

Even performing ordinary worldly good meets with many adverse conditions, so how much more so when one brings forth the supramundane mind to seek the path of awakening, provoking them to arise—how could one withstand them? Without the inconceivable secret efficacy, none can dispel them.
