(Spirit Rock Meditation Center) This style of meditation practice is designed to support both the strengthening of mettā (loving kindness) and samādhi (concentration). The kind and benevolent tone of the brahmavihārās (sacred dwellings) carries a deep beckoning of our hearts to be whole and steady, so these are wonderful and meaningful qualities to use for samādhi/concentration. After many days of practicing we can taste our hearts becoming whole and can better see the possibility of letting go of old habits based in greed, insecurity and hatred.
