This tiny book “Zen Words for the Heart” includes a translation of the Heart Sutra with commentary by the 17th Century Zen Master Hakuin Ekaku in a Zen idiom, e.g. Hakuin’s commentary on the line “Form is no other than Emptiness, Emptiness is no other than Form” in the Heart Sutra:
“A nice hot kettle on a stew. He ruins it by dropping the couple of “Form and Emptiness” in . It’s no good pushing delicacies at a man with a full belly. Striking waves to look for water when waves are water”.
Recommended for readers interested in Hakuin’s commentary on the Heart Sutra.
