大毘盧遮那成佛經疏 9.17

9.17

"All phenomena are devoid of shape and form,
Serene, clear, and without turbidity;
Free of grasping and detached from speech,
They arise solely from causes and actions.
Knowing this phenomenon in such a manner,
Its self-nature is without defilement.
Making matchless benefit for the world,
You are born from the Buddha's heart."
