Key Zen and Buddhist Sutras: A Practical Guide

By Cory Zanoni ✶ 7 min read

Sutras are the foundational texts of Buddhism. There are countless sutras and each school of Buddhism has their own preferences. Any list of “key” texts is fraught (hi) but some major texts pop up again and again.

There’s no set order to reading the texts. You can follow your curiosity and get on fine.

A quick note: some of these texts are called suttas, some sutra. Here’s the difference:

Key Buddhist Sutras

The Four Noble Truths Sutta (Dhammacakkappavattana Sutta)

This is considered to be a record of the historical Buddha’s first sermon. It lays out the Four Noble Truths that form the foundation of Buddhist teaching:

  1. Life involves suffering and transience.
  2. This suffering is rooted in attachment to things that are transient.
  3. Letting go of these attachments can help soften our suffering.
  4. The Eightfold Path can help us let go of our attachments.

This text sets the core assumptions of other Buddhist practices and traditions. Even if they don’t explicitly refer to the text, its influence is in there somewhere.

The Breath-Mindfulness Sutta (aka the Anapanasati Sutta)

A key text for meditation and mindfulness of breathing.

The Anapanasati Sutta list sixteen steps of meditation practice, making it a practical guide for people new to meditation (or those further along in their practice).

It’s laid out in four stages:

  1. Awareness of the body.
  2. Awareness of feelings.
  3. Awareness of the mind.
  4. Awareness of mental qualities.

Taken together, the sutta takes you from observing your breath alone to observing yourself letting go. Step by step, you make your way through a rich, nuanced practice. It’s demanding.

It also lays out the Buddha’s four foundations of mindfulness:

  1. Observing the body in the body.
  2. Observing the feelings in the feelings.
  3. Observing the mind in the mind.
  4. Observing the objects of the mind in the mind.

And then seven factors of awakening:

  1. Mindfulness.
  2. Investigation.
  3. Energy.
  4. Joy.
  5. Ease.
  6. Concentration.
  7. Letting go.

All in all, this sutta is a detailed guide for meditation and, by extension, mindfulness. You could base your practice around this teaching and be set for a while.

It’s also a great starting point for zazen – sitting meditation of Japanese Zen.

The Discourse on the Establishing of Mindfulness (aka the Satipatthana Sutta)

A fantastic introduction to mindfulness.

The Satipatthana Sutta presents a mindfulness practice around four objects of awareness, as described in the Anapanasati Sutta:

It starts with the breath and, step by step, builds to letting go. You investigate every part of your body (in both life and death), all the feelings you experience, the qualities of mind you become aware of and, finally, how you perceive, well, everything.

The sutta breaks our perceptions into a few different categories:

Pair the Satipatthana Sutta with the Anapanasati Sutta and you have a great foundation for a Buddhist practice.

The Loving-kindness Sutta (aka the Metta Sutta or Karaṇiya Metta Sutta)

Loving-kindness meditation is one of the more popular Buddhist teachings. This text lays out its core tenants.

It’s a practical guide to developing a kindhearted approach to yourself, other people and the world at large – built around a wish that “all beings be happy and safe”. The goal is a sense of love that doesn’t discriminate, which helps foster a sense of ease.

The text lists lays out moral guidance as well. Despite being about wishing that all be “happy and safe”, the text opens with a call for practitioners to be upright, honest, gentle and more. People need to be “skilled in the good”.

It’s a practice, after all. Loving-kindness meditation can help you get there. The Metta Sutta is aspirational in that sense. It helps you grow the muscle of kindness.

Key sutras in Zen Buddhism

The Diamond Sutra (Vajracchedikā Prajñāpāramitā Sutra) The full name translates roughly as “the diamond that cuts through illusion.” Honestly, strong name.

The Diamond Sutra is a dialogue between the Buddha and his disciple Subhūti. It’s short and the back-and-forth discussion makes it an easy read – but it’s also deliberately frustrating to read in the way that good Zen teaching tends to be. It undermines each concept it builds up: form is emptiness; the Buddha insisting he has nothing to teach.

It speaks to not-self (the idea that there’s no set, unchanging self), the emptiness of all things or concepts, and the importance of supporting others on their path to liberation.

At its core, the Diamond Sutra is about trying to experience reality for what it is behind the concepts we use to describe reality. Hence the audacious name, really.

The Heart Sutra (Prajñāpāramitāhṛdaya Sutra) This is one of the most widely recited texts in Mahayana Buddhism: it’s short enough to memorise and insightful enough to sit with.

The Heart Sutra shares the “perfection of wisdom” teachings. Its most well-known line. “form is emptiness, emptiness is form”, also appears in the Diamond Sutra.

It explores that emptiness through the five aggregates of human existence:

  1. Form.
  2. Feeling.
  3. Perception.
  4. Mental formations.
  5. Consciousness.

(Buddhism loves a list.)

Much like the Diamond Sutra, the Heart Sutra hopes to foster wisdom with compassion. They’re about emptiness, sure, but neither text is nihilistic. They’re about liberation for all (and the work of ensuring that).

Despite being short, there’s a lot in the Heart Sutra. You can sit with each line for a while. There’s no rush.

The Platform Sutra of the Sixth Patriarch The Platform Sutra has one major difference to the others on this: it’s a collection of teachings attributed to Huineng – not the Buddha.

Huineng was the sixth patriarch of Chan Buddhism (the Chinese tradition that led to Zen). The Platform Sutra is a collection of the school’s early teachings.

Like many figures in religious history, Huineng has become something of a legendary figure in Buddhism but he’s a key figure in Zen all the same. According to tradition, he was an illiterate layman who achieved sudden enlightenment.

The Platform Sutra reflects that experience. It focuses on a direct interaction with reality over intensive study of religious texts or by performing arcane rituals.

Across ten chapters, the Platform Sutra hits a few core themes of Zen:

  1. All individuals have an innate Buddha nature. It’s just hidden by attachments and delusions.
  2. Enlightenment can be achieved suddenly.
  3. Meditation is about that your mind is doing, not how you’re sitting.
  4. The limits of binary thinking.

All in all, the Platform Sutra is about trying to tap into reality and your nature as is.

Going further

This is just a quick skim over the surface of Buddhist texts. You could spend a lifetime just reading everything available to you.

Investigation and curiosity are part of Buddhist practice (and they add a sense of lightness, personally). It’s easy for that to default to “read everything, know everything” without ever directing that energy onto yourself, your assumptions or your actions.

In other words: yes, there are a lot of sutras you could read. But don’t let that become another barrier to the practice.

A healthy distrust of the scriptures and unearned authority are as important in Zen as curiosity. Read some texts, see what you think and take them to the cushion. Just remember to live as you go.
