Wheel of Life

Early Buddhist Foundations

The Wheel of Life illustration that we see everywhere these days is an existing linguistic concept from the early days but was formalised and enhanced later in Tibet after Buddhism was introduced in the 6th century.

Bhavacakra/bhavacakka was already an established Buddhist concept – a metaphor for cyclic existence found in Indian Buddhist texts in both Sanskrit and Pali. The linguistic term and the basic idea of the “wheel of becoming” predates Tibetan Buddhism. But it did not yet have the distinct structure that makes it a visual teaching tool.

Terminology

In Pali it’s bhavacakka, in Sanskrit it is bhavacakra.

• bhava = becoming, existence
• cakka = wheel (Sanskrit: cakra)
• So bhavacakka = wheel of becoming/existence

There are references to it in Pali texts like the commentaries and some suttas, but it’s used as a metaphorical or conceptual term for the cycle of rebirth/samsara, not as a reference to a specific diagram. The term captures the idea of beings revolving through existence, driven by craving and karma.

Tibetan Innovation

Tibet took this existing concept and created a formalised visual representation of it. They standardised a specific diagram that became a teaching tool. They took the pre-existing wheel metaphor and developed it into a detailed teaching device that combines multiple Buddhist ideas –the twelve nidanas, six realms, three poisons, etc– into one comprehensive image. Although there is doubt that Tibet developed this format from scratch, no evidence of Indian forerunners has survived.

The Tibetans didn’t invent the term or the underlying idea – they seem to have organised and expanded it into the particular artistic form we know today.

Buddhist Teachings vs. Visual Design

The individual elements –dependent origination, the realms of rebirth, the three poisons, karma– are all pan-Buddhist teachings found across traditions and traceable to Indian Buddhism. But the specific visual design where all these elements are combined into that particular layout with its characteristic arrangement (the six-sectioned wheel, Yama holding it, the twelve nidanas illustrated sequentially around the outer rim, the three animals at the centre, etc.) is a Tibetan innovation.

Formation of the Tibetan Visual Standard

Tibetans selectively visualised Buddhist ideas graphically. The Wheel of Life (‘khor lo’i srid pa or srid pa’i ‘khor lo) emerges from this context as an instructional chart that brings together multiple scriptural frameworks:

• The three poisons at the hub (showing the motivational roots of samsara).
• The six realms in the middle circle (rebirth destinations).
• The twelve nidānas as the outermost ring (dependent origination).
• The whole wheel held by Yama, symbolising impermanence and death.

This organised composition appears in Tibetan monastic art between the 11th and 13th centuries, coinciding with the rise of systematic learning in India’s late Buddhist monasteries (Nālandā, Vikramaśīla) but finding its mature visual expression only in Tibet. It was traditionally placed at the entrances to monasteries but has become a mainstay of Tibetan thangka painting.

The Absence of Indian Precedents

There’s no evidence of this specific visual formula existing in Indian Buddhist art. Indian Buddhism certainly used wheel imagery (the dharmachakra being the most obvious example), and depicted various Buddhist concepts visually, but not this particular teaching diagram.

Tibetan Contributions

Tibetan Buddhism can be credited with:

• Bringing together multiple Indian ideas into one coherent visual teaching tool.
• Standardising the format across monastic and artistic traditions.
• Using it as a memory aid and teaching framework for explaining karma, rebirth, and dependent origination in unified form.

Conclusion

The Tibetan tradition took these shared Indian Buddhist teachings and created a distinctive visual teaching tool that packages them together in a specific way. It’s become so iconic that people sometimes assume it must be ancient or pan-Buddhist, but the archaeological and art historical evidence shows this particular form developing in Tibet.

There is shared doctrinal content but a specific tradition’s innovation in how to represent and teach that content. The bhavacakra as we recognise it is definitively Tibetan Buddhist visual culture, even though it illustrates teachings common to Buddhism more broadly.

Monasteries have developed comprehensive explanations of how the elements interact and relate to each other so Tibetan monks have a deep understanding of the functioning of The Wheel of Life.
