9.67

答：初明塔涌，欲表非是孤墳，有靈覺故發聲也。次開塔竟復發聲者，前雖發聲猶未見形，恐前所發者非是佛聲，故現形表口自發聲。最後發聲者，多寶不滅雖彰，釋迦不生未顯，故携之並坐，欲顯釋迦不生故復發聲也。

Answer: First, explaining the welling up of the stūpa is intended to represent that it is not an empty tomb; because there is spiritual awareness, he emits a sound. Next, after the stūpa is opened, he speaks again: previously, although he emitted a sound, his form was not yet seen, and it was feared that what was emitted earlier was not a buddha's voice; therefore, he manifests his form to show his mouth personally emitting the sound. Finally, as for speaking the last time: although Prabhūtaratna's non-extinction has been displayed, Śākyamuni's non-arising has not yet been revealed; therefore, he takes his hand and sits beside him, speaking again in order to reveal Śākyamuni's non-arising.
