One indivisibility

In the realm of true inconceivability,
All is one indivisibility;
It is the unimaginable, the unthinkable,
Vairocana manifesting as all.

Appearing in myriad forms,
Vairocana is simultaneously everywhere;
The radiance of infinite intelligence,
The great body of Vairocana.

Tu-shun (557-640 CE) the First Patriarch of the Hua-yen school
