仁王般若經疏 2.117

2.117

"Conventional truth arises like an illusion or transformation,
just like flowers in the sky;
like a shadow without three hands,
it falsely exists because of causes and conditions.
An illusion seeing an illusion,
is called the illusory truth of sentient beings;
when an illusionist sees illusory phenomena,
in true reality, both are completely absent.
This is called the contemplation of the Buddhas,
and the contemplation of bodhisattvas is also like this."
