大毘盧遮那成佛神變加持經 (Shubhakarasimha & Yixing 724) 6.32

6.32

"If fundamentally non-existent, yet arising in accord with the world,
How does one comprehend emptiness and bring forth this yogin?
If the intrinsic nature is thus, the name of awakening cannot be found;
A mind equal to space should arise, which is called the bodhicitta.
One should generate kindness and compassion, conforming to all worlds;
Abiding in the conduct of mere ideation, this is called the Buddhas.
You should know that ideation fabricates; contemplate this as the emptiness of emptiness.
Just as the counting method below proceeds, differing by increments of one,
Diligent hero, emptiness is also like this, increasing in successive order;
Namely, these syllables such as 'A' are empowered by spontaneous wisdom."
