' The source of all Buddhas '...

"The light of lights is not blue, yellow, red, white or black.

It is not matter, not mind.

It is not existent, not nonexistent.

It is not a phenomenon resulting from causes.

It is the source of all Buddhas, the basis of practicing the Way of enlightening beings, fundamental for all Buddhists."
