‘Positive’ emotions are essentially those that are not self-centred. They are more outgoing and orientated towards others, though their positivity naturally includes ourselves. The most fundamental of these positive emotions is metta — a Pali word which means unlimited loving-kindness or benevolence. The development of metta (Metta Bhavana) is generally the first practice taught to cultivate this aspect of the system of meditation.
Metta Bhavana is one of a traditional set of four practices that cultivates different aspects of positive emotion. When, with metta, we encounter pain and suffering, the well-wishing naturally becomes compassion. When we encounter happiness, it becomes sympathetic joy; we delight in someone else’s good fortune. When we contemplate all the ups and downs of human (and non-human) existence, the positive emotion becomes equanimity; this is a steady, empathic and unshakeable positivity, which embodies deep insight into the human condition.
Achievement of a reasonable degree of integration and positive emotion (samatha) is the basis for the next two aspects of the system, involving the cultivation and realisation of insight.
