The Heart Sutra has been transmitted in a short form (about 14 slokas) and a longer form (about 22 slokas). The latter redaction, in 22 slokas, appears to be the more original (since it more neatly adheres to the earlier source texts, such as the Astasahasrika-prajnaparamita-sutra) and it is this text that we present herein.
Thus I have heard, at one time, the Buddha dwelt at Shravasti, in the Jeta Grove, in the Garden of the Benefactor of Orphans and the Solitary, together with a gathering of great Bhikshus, twelve hundred fifty in all, and with all of the Bodhisattvas, thirty-eight thousand in all.
1. Mind is the forerunner of (all evil) states. Our life is the creation of our mind. If one speaks or acts with impure mind, suffering follows one as the wheel of the cart follows the draught-ox that draws the cart. (1)
Thus I have heard. The Blessed One once appeared in the Castle of Lanka which is on the summit of Mt. Malaya in the midst of the great Ocean. A great many Bodhisattvas-Mahasattvas had miraculously assembled from all the Buddha-lands, and a large number of bhikshus were gathered there.
This is what I once heard. The Lord was dwelling in the Jetavana of Anathapindika's park in Sravasti. King Prasenajit of Kosala and his Queen Mallika had believed in the Buddha's Doctrine for only a short time. Now they engaged in conversation.
"O great king, our daughter Queen Srimala is profound and clever. If she were just to see the Buddha, she would understand the doctrine with little difficulty and she would have no doubts about the Buddha's teaching."
Aesop's fables enjoy worldly fame, while almost unknown are Sakyamuni's fables. Obviously there is a difference between them as far as the nature of the two books are concerned. the former tells stories to teach moral principles, whereas the latter illustrates a religious precept to reflect the nature of human being. Therefore, the latter is strictly a religious literature.
Thus have I heard. At one time, the Buddha stayed in the palace of the Dragon King of the Ocean together with an assembly of eight thousand great Bhikshus and thirty- two thousand Bodhisattvas and Mahasattvas altogether. At that time the World Honored One told the Dragon Kingsaying: Because all beings have different consciousness and
thoughts, they perform too different actions and as a consequence there is the turning around in all the different courses of existence.
Thus have I heard. One time the Buddha was staying at the city of Kusinagara, the birthplace of the great worthy, on the shore of the Ajiravati River between a pair of Sala trees. At that time, the World Honored One was accompanied by a great bhiksu congregation numbering eighty nayutas of kotis  of people, encircling him front and back.
