Prima facie, the association of the Tibetan term for ‘compassion’ with action stands at odds with the Graeco-Roman association of ‘compassion’ with emotion. In the Indo-Tibetan tradition, ‘compassion’ is, however, also closely associated with the emotion described as ‘loving-kindness’ (Sanskrit* metta*) while Aquinas’ construal of compassion as a passio animae, an affective reaction which brings about a change in bodily state, is seen by him as the basis, when joined with reason, of its correlative virtue, caritas. Arguably, therefore, the meanings of snying rje and misericordia, both of them translated as* ‘compassion’,* are not so far apart as they might seem at first.
