The Heart Sutra
For imprints to realise emptiness
Thus I have heard: at one time, the Blessed One was dwelling in Rajagriha on Massed Vulture’s Mountain together in one method with a great assembly of monastics 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, Venerable Shariputra said to Superior Avalokiteshvara, the bodhisattva, the great being, "How should a child of the lineage train who wishes to engage in the practice of the profound perfection of wisdom?"
Thus he spoke, and Superior Avalokiteshvara, the bodhisattva, the great being, replied to Venerable Shariputra as follows:
"Shariputra, 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 empty; 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 compositional 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 up to no mind element and also up to no element of mental consciousness. There is no ignorance and no exhaustion of ignorance, and so forth up to 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, 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 awakening.
"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:
Tayata gate gate paragate parasamgate bodhi soha
"Shariputra, a bodhisattva, a great being, should train in the profound perfection of wisdom like this."
Then the Blessed One arose from that concentration and said to Superior Avalokiteshvara, the bodhisattva, the great being, that he had spoken well. "Good, good, O child 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, Venerable Shariputra, Superior Avalokiteshvara, the bodhisattva, the great being, and 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.
If one is constrained by time, the following can be recited instead of The Heart Sutra
from The Precious Garland by Nagarjuna:
A person is not earth, not water,
Not fire, not wind, not space,
Not consciousness, and not all of them.
What person is there other than these?
Just as a person is not real
Due to being a composite of six constituents,
So each of the constituents also
Is not real due to being a composite.
The elements do not themselves exist individually,
So how could their own individual characters exist?
What do not themselves individually exist cannot predominate.
Their characters are regarded as conventionalities.
Also from Root Wisdom by Nagarjuna - Chapter 24
18. Whatever is dependently co-arisen that is explained to be emptiness.
That being a dependent designation is itself the middle way.
19. Something that is not dependently arisen such a thing does not exist.
Therefore a nonempty thing does not exist.
