The Heart Sutra
(The Prajna-Paramita-Hrdaya Sutra)
When Bodhisattva Avalokitesvara practices the profound Prajna-paramita, he intuitively realizes that the five aggregates (skandhas) are of Sunyata nature thus securing his deliverance from all distress and sufferings.
Sariputra! Form (rupa) does not differ from Sunyata, nor Sunyata from form. Form is identical with Sunyata (and) Sunyata is identical with form. So also are reception (vedana), conception (sanjna), mental conduct (samskara) and consciousness (vijnana) in relation to Sunyata.
Sariputra, the Sunyata nature of all things is neither created nor annihilated; neither impure nor pure; and neither increasing nor decreasing.
Therefore, in Sunyata, there is neither form (rupa), reception (vedana), conception (sanjna), mental conduct (samskara), nor consciousness (vijnana); there is neither eye, ear, nose, tongue, body nor mind; there is neither form, sound, odor, flavor, feeling nor idea; there are no such things as the eighteen realms of sense (dhatus) from the realm of sight up to that of the faculty of mind (vijnana); there are no such things as the twelve links in the chain of existence (nidanas) from ignorance (avidya) with also the end of ignorance up to old age and death (jaramarana) with also the end of old age and death; there are no (such things as) the four noble truths and there is neither Wisdom nor obtainment.
Because of no obtainment, Bodhisattvas who rely on Prajna-paramita, have no hindrance in their minds, and since they have no hindrance, they have no fear, are free from perversive and delusive ideas and attain the Ultimate Nirvana.
All Buddhas of the past, present and future attain the Full Enlightenment (anuttara-samyak-sambodhi) by relying on Prajna-paramita. So we know that Prajna-paramita is the great supernatural Mantra, the great bright, unsurpassed and unequalled Mantra which can truly and without fail wipe out all sufferings.
Therefore, He uttered the Prajna-paramita mantra which reads:
Gate, Gate, Paragate, Parasamgate Bodhi Svaha!
