TREE OF TRUTH
Deep Roots — R2 (Buddhist Thought)

Gautama Buddha

c. 5th–4th century BCE — India/Nepal

ROOTSBRANCHES
The Core Question

What causes suffering — and can awareness itself be liberated from it?

Primary Contribution

Established the Anatta (no-self) teaching: the five aggregates constituting a person are not a self, not mine, not what I am. When identification with these aggregates ceases, suffering is extinguished.

Key Ideas

  • Anatta (no-self): the five aggregates are not a self, not mine, not what I am
  • Four Noble Truths: suffering exists, has a cause (craving), can cease, and there is a path
  • The Noble Eightfold Path: right view, intention, speech, action, livelihood, effort, mindfulness, concentration
  • Dependent Origination (Pratityasamutpada): all phenomena arise in dependence on causes and conditions
  • The middle way: between extreme asceticism and indulgence; between existence and non-existence

Signature Quote

Mind is the forerunner of all states. Mind is chief, mind-made are they. If one speaks or acts with a pure mind, happiness follows, as a shadow that never departs.

Further Sayings

All conditioned things are impermanent — when one sees this with wisdom, one turns away from suffering.
Do not believe in anything simply because you have heard it. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.
He who sees dependent co-origination sees the Dharma; he who sees the Dharma sees dependent co-origination.

Legacy & Influence

The Buddha's teaching gave rise to the most geographically extensive spiritual tradition in history — from India through Southeast Asia, China, Japan, Tibet, and now the West. His Anatta doctrine is the deepest challenge to the materialist assumption of a persistent self, and anticipates by 2500 years the no-self findings of cognitive neuroscience (Metzinger, Seth). The mindfulness revolution in clinical medicine is a direct secularization of vipassana practice.
