The Heart Sutra (Prajna Paramita Hrdaya Sutra)

When the Bodhsattva Avalokitesvara
Was practising the profound perfection of wisdom,
He illiminated the Five Aggregates,
And saw in their own being to be empty.

Sariputra, form is here emptiness,
Emptiness is form;
Form is no other than emptiness,
Emptiness is no other than form;
That which is form is emptiness,
That which is emptiness is form.
The same is true of feelings, perception,
Mental formations and consciousness.

Sariputra, all things are marked with emptiness:
They are not born or destroyed;
They are not impure or pure;
Nor do they wax or wane.

Therefore, Sariputra, in emptiness,
There is no form, no feeling, no perception,
No mental formation, no consciousness;
No eye, ear, nose, tongue, body, mind;

No form, sound, smell.
taste, touch or objects;
No eye element and so forth
Up to mind consciousness element.

There is no knowledge, no ignorance,
No extinction of knowledge,
No extinction of ignorance,
And so forth up to old age and death,
No extinction of old age and death;
There is no suffering,
No cause, no end, no path;
There is no knowledge, and no attainment.

Therefore, Sariputra, because nothing is attained,
The Bodhisattva who dwells in the perfection of wisdom
Has his mind free from obstacles,
With a mind free from obstacles,
He overcomes fear
And goes beyond perverted views,
And attains to Nirvana!

All the Buddhas of the three periods of time,
Through the incomparable Perfection of Wisdom,
Attain to the Perfect and Highest Enlightenment!

Therefore, one should know the Perfection of Wisdom
As the great mantra;
The mantra of great knowledge,
The unsurpassed mantra,
The mantra which can truly and without fail
Allay all sufferings.
This mantra is proclaimed in the Perfection of Wisdom.
It run thus:
GATE GATE PARAGATE PARASANGATE BODHI SVAHA (X 3)

The Four Noble Truths

After gaining Enlightenment, The Buddha discovered the Four Noble Truths.

1. All being are subjected to sufferings (Dukkha)

The Buddha said, "Birth is suffering, Life is suffering, Sickness is
suffering, death is suffering, decay is suffering, to be parted from
love ones is suffering and to be united with the unpleasant is
suffering."

2. Sufferings arises from desires and cravings.

All of us crave for pleasant feelings and sensations, and also the
desire to avoid unpleasant ones. These sensations can be physical or
psychological, and sufferings occur when these desires or cravings are
not met.

3. Sufferings can be overcome by the elimination of desires and cravings.

Nibbana is the state of peace where all greed, hatred, and delusion,
and thereby sufferings have been destroyed.

4. There is a way out of suffering or dukkha,which is the Noble Eightfold
Path.

Sufferings can be reduced, weakened and finally destroyed and Nibbana
thereby achieved, by following this path taught by the Buddha
