These verses are from part of the noon service we chant every day. Daehaeng Kun Sunim translated this text from the Chinese character to modern Korean, but also did it according to the underlying meaning. The result is an incredible manual for spiritual practice.
My one mind is the Bodhisattva of Compassion,
so I return to my one mind and rely upon it.
If I believe and follow only my one mind,
I can become one with continuously arising unenlightened beings,
and in so doing, save them all.
