Enlightenment

*information from Rigpa Shedra site

May all sentient beings have happiness and the causes of happiness.
May all sentient beings be free from suffering and the causes of suffering.
May all sentient beings never be separated from the happiness which is without suffering.
May all sentient beings abide in equanimity, free from both attachment and hatred, holding some close and others distant.
