In the Buddhist tradition, one cultivates metta, or lovingkindness. It is a practice of wishing yourself and others freedom from suffering as well as happiness and peace.
Practice a brief metta meditation today:
May I be happy. May I be well. May I be peaceful and at ease.
May you be happy. May you be well. May you be peaceful and at ease.
May all beings be happy. May all beings be well. May all beings be peaceful and at ease.
