馬腦（案馬腦梵音謂之阿溼嚩揭波言阿溼嚩者此云馬也嚩音符何反揭波者腦也藏也若言阿溼摩揭波此云石藏案此寶出自石中故應名石來以馬聲濫石藏聲濫腦故謬云馬腦）。

Agate (In Sanskrit, agate is called aśvagarbha. Aśva means horse here; garbha means brain or womb/receptacle. If pronounced aśmagarbha, it means 'stone receptacle'. As this gem comes from within rock, it should be called 'stone receptacle'. Because the sound for 'horse' [aśva] was confused with 'stone' [aśma], and 'receptacle' [garbha] was confused with 'brain' [gao/nao], it was mistakenly called 'horse-brain' [agate]).
