From The Sutra of the Noble Collection:

Know the five skandhas are like an illusion
Don’t separate the illusion from the skandhas
Free of thinking that anything is real—
This is perfect wisdom’s conduct at its best!

From The King of Samadhi Surtra:

All the images conjured up by a magician
The horses, elephants and chariots in his illusions
Whatever may appear there, know that none of it is real
And it’s just like that with everything there is!
