I learned about Jijang Bosal (Jizo in Japanese). Being a member of the Kwan Um School of Zen, we get chanting requests for deceased to JiJang Bosal.

I thought it would be nice to learn the Heart Sutra chant and to write it out in Hanja. I know it is one of the shortest sutras, but I now realize that it is a big task for me because I don't know most of the Chinese characters.
I wonder why Korean monks chant in Chinese? Maybe just a historical hold over?
