The Heart Sutra

The Heart Sutra is one of the shortest and best-known Buddhist texts. Its full Sanskrit name is Prajñāpāramitāhṛdaya, “the heart of the perfection of wisdom”. In its common short form it fits on a single page, yet it is chanted every day in temples across East Asia, Tibet and Vietnam, and in Zen groups around the world.

Where it comes from

The Heart Sutra belongs to the Perfection of Wisdom (prajñāpāramitā) literature, a large family of Mahayana texts on emptiness. It condenses their message into a few lines. It survives in a shorter and a longer version, in Sanskrit, Chinese and Tibetan. The Chinese version associated with the pilgrim and translator Xuanzang, from the seventh century, is the one most widely chanted. Scholars continue to discuss exactly where and when the text was first composed.

What it says

The sutra presents Avalokiteśvara, the bodhisattva of compassion, practising deep wisdom. He sees that the five aggregates, the components of a person (form, feeling, perception, mental formations and consciousness), are all empty. Seeing this, he goes beyond suffering.

He then explains this to Śāriputra, one of the Buddha's chief disciples, in the famous line that form is emptiness and emptiness is form. Emptiness (śūnyatā) here does not mean nothingness. It means that nothing exists independently or by its own nature; everything arises in dependence on other things.

The text goes on to say that, in emptiness, the familiar lists of Buddhist teaching, such as the senses, the twelve links and the Four Noble Truths, are also without fixed essence. This is not a rejection of the teachings but a reminder not to cling even to them. Bodhisattvas who rely on the perfection of wisdom have minds without obstruction, and so without fear.

The mantra

The sutra ends with a mantra, given in Sanskrit as gate gate pāragate pārasaṃgate bodhi svāhā. It is often rendered “gone, gone, gone beyond, gone completely beyond, awakening, so be it”.

Using it

Many people first meet the Heart Sutra as a chant. Reading a careful translation alongside a commentary helps, because the text is very compressed. Different traditions, including Zen, Tibetan and Chinese schools, offer their own rich explanations of it.
