大方廣圓覺修多羅了義經略疏 1.661

1.661

「世尊！若彼眾生無正方便及正思惟，聞佛如來說此三昧，心生迷悶，即於圓覺不能悟入。」

“World-Honoured One, if those sentient beings lack correct expedients and correct reflection, when they hear the Buddha, the Tathāgata, expound this samādhi, their minds will become confused and bewildered, and they will not be able to awaken and enter into perfect enlightenment.”
