I am reading a version The Sixth Patriarch's Dharma jewel platform sutra : with the
commentary of Venerable Master Hsuan Hua, English translation by the Buddhist Text Translation Society.

In the introduction it says this:
While still in India, Patriarch Bodhidharma sent two of his disciples, Fo T’o and Yeh She, to China to transmit the sudden enlightenment Dharma door. But no one, not even Chinese Bhikshus, would speak to them. So they went to Lu Mountain where they met the Great Master Yüan Kung, who lectured on mindfulness of the Buddha.
Master Yüan asked, “What Dharma do you transmit that causes people to pay you so little respect?” Fo T’o and Yeh She could not speak Chinese, so they used sign language instead. Raising their arms in the air, they said, “Watch! The hand makes a fist and the fist makes a hand. Is this not quick?” Master Yüan replied, “Quick indeed.” “Bodhi (enlightenment) and affliction,” they said, “are just
that quick.” At that moment, Dharma Master Yüan became enlightened, realizing that originally Bodhi and affliction are not different, for Bodhi is affliction and affliction is Bodhi. He made offerings to Fo T’o and Yeh She, and shortly thereafter, the two Indian Bhikshus died on the same day, in the same place. Their graves may still be seen at Lu Mountain.
How can affliction and Bodhi not be different when affliction causes suffering and Bodhi does not?
