For example, we eat without being hungry and we can't stop. True joy contains peace and harmony, while fake joy is a fever. Indulging in the five sensual desires of money and material possessions, fame, sex, food, and sleep is a fever. Eventually no sensual desire can cover up our suffering. It just waters the seeds of further suffering.
Mindfulness practice is a way to transform ill-being and suffering.
Monks and nuns do not seek happiness outside of themselves. They embrace their ill-being and transform it. They want to practice full time and to live in a temple or practice center with the sangha. Their beginner's mind brings harmony and peace to themselves and others, and it must be nourished each day. Bodhicitta is the mind of enlightenment, awakening, understanding, and love.
