Bhavacakra: The Wheel of Life (Srid-pa’i ’khor-lo)

How to Read the Four Concentric Rings from Hub to Rim

TL;DR · In Plain Words

Painted on the outer vestibule wall of nearly every Tibetan monastery according to instructions in the Vinaya (Toh 3), the Wheel of Becoming maps how habitual reactivity spins into suffering—and precisely where awareness steps free.

OUTSIDE THE WHEEL · LIBERATION Impermanence is not doom: freedom lies outside the rim. 01 · HUB: THREE POISONS Rooster (craving), snake (aversion), pig (ignorance). 02–03 · KARMA & SIX REALMS Bright/dark choices & six psychological states. 04 · RIM: TWELVE LINKS (NIDĀNAS) Break craving where feeling arises to halt the chain.

The Earliest Visual Infographic in Buddhist History

According to the Mūlasarvāstivāda Vinaya preserved in the Tibetan Kangyur (Toh 3), King Udrāyana once sent King Bimbisāra a priceless jeweled armor. Wanting to return something of even greater value, Bimbisāra asked the Buddha what gift could awaken someone who had never met a teacher. Śākyamuni personally specified the layout of a five-spoked (later six-spoked) wheel and instructed that it be painted on monastery entrance porches so ordinary passersby could grasp the entire Dharma visually.

Read from the center outward, the whole mechanism fits together with surgical clarity: at the very hub (Ring 1), a rooster (craving), a green snake (hatred), and a dark pig (ignorance) bite one another’s tails—showing how blindness fuels attachment and anger in a closed loop. Around the hub (Ring 2), a bright left half-circle shows beings rising through ethical mindfulness, while a dark right half-circle shows beings pulled downward by destructive compulsion.

Why Impermanence Holds the Wheel—and Why the Buddha Points Outside It

Ring 3 expands into the Six Realms (gods, warring demi-gods, humans, animals, hungry ghosts, and hells)—read in Tibetan lojong manuals both cosmologically and as six psychological states a human mind can cycle through in a single afternoon. Notice that inside every single realm stands an emanation of Avalokiteśvara or the Buddha: holding a lute to wake complacent gods from pride, armor among demi-gods, an alms bowl among humans, a book among animals, nectar among hungry ghosts, and purifying flame/water in the hells.

Around the outer rim (Ring 4) run twelve scenes of the Twelve Links of Dependent Origination—beginning with a blind elder (ignorance). Clutching the entire wheel in claws and fangs is Yama, Lord of Impermanence: terrifying only when we pretend things last forever, yet actually holding up an honest mirror. Best of all, look outside the wheel in the upper corners: Śākyamuni Buddha stands free in open sky pointing his finger toward a cool full moon—visually promising that because the wheel is built from conditions, ceasing to grasp between “pleasant/unpleasant feeling” (Link 7) and “craving” (Link 8) sets the mind free.

How It Is Practiced in Living Tradition

Monastic guides traditionally pause with pilgrims and children at the porch mural before entering the shrine room, turning abstract Abhidharma philosophy into vivid self-reflection.

Common Questions & Clarifications

Why is the pig at the very center sometimes shown with both the snake and rooster emerging from its mouth?

That detail illustrates a precise Buddhist insight: both clinging attachment (rooster) and hostile aversion (snake) grow out of fundamental ignorance (pig)—misperceiving interdependent things as isolated “me” versus “them.”
