觀音義疏 2.49

2.49

答：佛身多種，若應化非真佛，亦非說法人。真佛者，據妙覺法身，究竟極地毘盧遮那乃名真佛。真佛淵遠，不可說示，云何能解？如妙音所作，文殊不知，況下地凡夫為示真身耶？如為牛羊彈琴，不如作蚊虻之聲。

Answer: Buddha bodies are of many kinds; if they are responses and transformations, they are not the real Buddha, nor are they the speaker of Dharma. As for the real Buddha, based upon the dharma body of wondrous awakening, Vairocana at the ultimate, supreme stage is indeed called the real Buddha. The real Buddha is profound and distant, impossible to speak of or display; how could anyone understand him? Just as Mañjuśrī did not recognize what Gadgadasvara did, how much less could the real body be shown to ordinary beings on lower planes? It is like playing the lute to cows and sheep: it would be better to make the sound of mosquitoes and gnats.
