“The cause of suffering is our attachment to craving (for wealth, status, possessive love, and so on) and to aversion (for example, to hurt feelings, discomfort, pain). Freedom (or nirvana) comes from extinguishing attachment, a process aided by practices such as mindfulness and loving-kindness meditation. In this nonattached ideal, longing seems a highly problematic condition. As one Buddhist website put it, “After a lot of training with the Buddha’s teachings, we tend to recognize longing as an unproductive mindstate and just move on from it to whatever is actually present.”
