32 The mystical syllable hū is used for concentrating the thoughts upon God. Originally it is the Arabic third person personal pronoun “he” i.e. “He, God" (Cf § 126). The verse contains a beautiful double image: Firstly, when we concentrate our thoughts upon Him, all else disappears from the mirror of the mind, but also, if we place ourselves before a mirror and say hoo our breath will blur the mirror's surface and all images will disappear.
