Metta practice is a form of mindfulness meditation, based on the Buddhist concept of loving-kindness, that works to cultivate qualities of beneficence, compassion, empathetic joy, and equanimity towards ourselves, others, and the world. Practicing Metta has been proven to reduce stress, anxiety, depression, increase positive emotion, and overall wellbeing. The technique can be practiced formally, by attending a class or retreat, or informally, by simply taking moments of appreciation and gratitude during everyday activities.
