Below text is a brief practice around one of the most profound sutras: the Heart Sutra.

'THE GREAT MOTHER'
TAKING REFUGE AND GENERATING BODHICITTA
Until we achieve enlightenment, I and all sentient beings,
Go for refuge to the Buddha, Dharma and Sangha.
Trough the virtues I collect by giving and the other perfections,
May I become a Buddha for the benefit of all. (3X)

PRELIMINARIES
NAMO - Guru, Teacher, Blessed One and the Great Mother Prajnaparamita, surrounded by your Sons, the Buddhas of the ten directions and all Bodhisattvas; I prostrate to this assembly, make offerings and go for refuge, please empower me with your blessings.

THE SUTRA OF THE HEART OF THE PERFECTION OF WISDOM
Arya-Bhagavati-prajnaparamita-hrdaya-sutram (Homage to the holy Perfection of Wisdom!)
Thus I have heard: At one time, the Blessed One was dwelling in Rajagriha on Massed Vultures Mountain, together in one method with a great assembly of monks and a great assembly of Bodhisattvas. At that time the Blessed One was absorbed in the concentration of the countless aspects of phenomena called Profound Illumination.
At that time also, Superior Avalokiteshvara, the Bodhisattva, the Great Being, was looking perfectly at the practice of the profound perfection of wisdom, perfectly looking at the emptiness of inherent existence of the five aggregates also.
Then, through the power of Buddha, the venerable Sariputra said to the Superior Avalokiteshvara, the Bodhisattva, the Great Being; "How should a son of the lineage train who wishes to engage in the practice of the profound perfection of wisdom?"
Thus he spoke, and the Superior Avalokiteshvara, the Bodhisattva, the Great Being, replied to the venerable Sariputra as follows;
"Sariputra, whatever son or daughter of the lineage wishes to engage in the practice of the profound perfection of wisdom should look perfectly like this: subsequently looking perfectly and correctly at the emptiness of inherent existence of the five aggregates also.
Form is emptiness; emptiness is form. Emptiness is not other than form; form also is not other than emptiness. Likewise, feeling, discrimination, compositional factors and consciousness are empty. Shariputra, like this, all phenomena are merely empty, having no characteristics. They are not produced and do not cease. They have no defilement and no separation from defilement. They have no decrease and no increase.
Therefore, Shariputra, in emptiness there is no form, no feeling, no discrimination, no compostional factors, no consciousness. There is no eye, no ear, no nose, no tongue, no body, no mind, no form, no sound, no smell, no taste, no tactile object, no phenomenon. There is no eye element and so forth, upto no mind element, and also upto no element of mental consciousness. There is no ignorance and no exhaustion of ignorance, and so forth, upto no ageing and death and no exhaustion of ageing and death. Likewise, there is no suffering, origin, cessation or path; no exalted wisdom, no attainment and also no non-attainment.
Therefore, Shariputra, because there is no attainment, all Bodhisattvas rely on and abide in the perfection of wisdom; their minds have no obstructions and no fear. Passing utterly beyond perversity, they attain the final state beyond sorrow. Also, all the Buddhas who perfectly reside in the three times, relying upon the perfection of wisdom, become manifest and complete Buddhas in the state of unsurpassed, perfect and complete enlightenment.
Therefore, the mantra of the perfection of wisdom, the mantra of great knowledge, the unsurpassed mantra, the equal-to-the-unequalled mantra, the mantra that thoroughly pacifies all suffering, since it is not false, should be known as the truth. The mantra of the perfection of wisdom is proclaimed:
TAYATHA: OM GATE GATE PARAGATE PARASAMGATE BODHI SVAAHAA
Sariputra, a Bodhisattva, a Great Being, should train in the profound perfection of wisdom like this."
Then the Blessd One arose from that concentration and said to the Superior Avalokiteshvara, the Bodhisattva, the Great Being, that he had spoken well. "Good, good, O son of the lineage. It is like that. Since it is like that, just as you have revealed, the profound perfection of wisdom should be practiced in that way, and the Tathagatas will also rejoice."
When the Blessed One had said this, the venerable Shariputra, the Superior Avalokiteshvara, the Great Being, that entire assembly of disciples, as well as the worldly beings - gods, humans, demi-gods and spirits -, were delighted and highly praised what had been spoken by the Blessed One.

RECITING THE MANTRA
TAYATHA OM GATE GATE PARAGATE PARASAMGATE BODHI SOHA
REQUESTS TO OVERCOME HINDRANCES
Great Mother, Prajnaparamita, and all the Buddhas ans Bodhisattvas of the ten directions, through the power of your blessings may these true words of mine be achieved. Just as before, when by contemplating the profound meaning of the perfection of wisdom and reciting its words, Indra overcame all the harm of maras, non-humans and so forth, in the same way, by my contemplating the profound meaning of the perfection of wisdom and reciting its words:

May all the harm of maras, non-humans and so forth be overcome.(clap)
May they become non-existent. (clap)
May they be pacified.(clap)
May they be thoroughly pacified.(clap)

DEDICATION PRAYER
May all kinds of interferences, diseases and possessing spirits be pacified,
May we be separated from unfavourable conditions,
And may we achieve favourable conditions and everything excellent.
Through this fortune may there now be happiness and health.
