The Perfection of Wisdom Heart Sutra

When Avalokiteshvara Bodhisattva was practising the profound perfection of wisdom, he illuminated the five aggregates and saw that they are all empty, then he ended all suffering.

Sariputra, form does not differ from emptiness, emptiness does not differ from form.
Form itself is emptiness, emptiness itself is form. Feeling, perception, mental formation, and consciousness are also such as this.

Thus Sariputra, all phenomena are empty of characteristics, nei­ther cre­ated nor destroyed, nei­ther de­filed nor pure, nei­ther in­crease nor decrease. Therefore Sariputra, in emptiness there is no form; no feeling; no perception; no mental formation; no consciousness; no eye, ear, nose, tongue, body, or mind; no form, sound, smell, taste, sen­sa­tion, or phe­nom­ena; no realm which is physically visible; even no realm of mind conciousness; no ig­no­rance; no ending of ig­no­rance; even no old age and death; no ending of old age and death; no suffering, origin, cessation, or path; no knowledge; no attainment. 

Be­cause there is no at­tain­ment, bod­hisattva relies on perfection of wisdom and his mind has no ob­struc­tion. Since there is no ob­struc­tion, he has no fear. After delusion is completely terminated, Nirvana is attained. By relying on perfection of wisdom, all Buddhas of the three periods attain unsurpassable complete enlightenment.

Therefore, know that perfection of wisdom is a great spiritual mantra, a great brilliant mantra, an unsurpassable mantra, and an unequalled mantra. It really can destroy all suffering. The mantra of perfection of wisdom is recited thus:

Gate Gate Paragate Parasamgate Bodhi Svaha.
