大方廣佛華嚴經隨疏演義鈔 89.34

89.34

疏三十二「訶婆（並上聲）字」，別譯為「訶嚩」。文中釋義「無緣召令有緣」，即會經也。《智論》云「若聞火字，即知一切法無音聲，以火夜此言喚來故。」

In the commentary on the thirty-second [syllable], 'hava' (訶婆, both rising tone), another translation has 'hava' (訶嚩). The explanation of the meaning in the text, 'summoning the conditioned when there are no conditions', is precisely the correlation with the sūtra. The Mahāprajñāpāramitopadeśa states: 'If one hears the syllable hva (火), one immediately knows that all phenomena are devoid of sound, because hvaya (火夜) here means summoning to come.'
