The four immeasurables
May all beings have happiness and the causes of happiness.
May all beings be free from suffering and the causes of suffering.
May all beings rejoice in the well-being of others.
May all beings live in peace, free from greed and hatred.
Each of the four verses corresponds to a mental state: loving kindess,
compassion, sympathetic joy, and peace (or equanimity). See the Metta Sutta page.
