3.184

五、不女音。佛住首楞嚴定，常有世雄之德，久已離於雌軟之心，故所出言聲能令一切聞者敬畏，天魔外道莫不歸伏，名不女音。

5. The not effeminate voice: The Buddha abides in the śūraṅgama samādhi and perpetually possesses the virtue of a hero of the world, having long departed from any weak or feminine mind; therefore, the words and sounds he emits are able to cause all who hear them to be reverent and awed, such that the heavenly Māras and non-Buddhists all submit; this is called the not effeminate voice.
