The Prajna Paramita Heart Sutra was translated from Sanskrit to Chinese by Tripitaka Master Hsuan Tsang, with commentary by Grand Master T'an Hsu, and Ven. Dharma Master Lok To. In six hundred scrolls, the Maha Prajna Paramita Hrydaya Sutra forms the core of the Maha Prajna Paramita. Grand Master T'an Hsu walked through the sutra line by line, delivering a clear and lengthy commentary on each one, and using many carefully picked examples along the way to make his discourse more relevant in terms of everyday life.
