(Spirit Rock Meditation Center) Equanimity is central to the Buddha's teachings and practices, and so underlies and supports both mindfulness and metta (loving-kindness). For Samma Sati, Right Mindfulness, to develop, equanimity needs to function to keep us connected with experiences even when they are difficult or challenging, to deepen insight into the true nature of reality. In metta practice, equanimity keeps the heart open when conditions are not ideal for kindness - and they are often not ideal!
