The twelve nidānas, causes or links, set out how suffering arises: ignorance, formations, consciousness, name-and-form, six senses, contact, feeling, craving, clinging, becoming, birth, and ageing and death. Traditionally they are read across three lives; they can also be traced in each moment. Tibetan art depicts them on the wheel of life.
