Lokah samastah sukhino bhavantu is a Sanskrit prayer or ancient mantra used for centuries. aThe simplest translation is: “May all beings everywhere be free and happy... And may the thoughts, words and actions of my own life contribute in some way to that happiness and to that freedom for all.”
lokah: location, realm, all universes existing now samastah: all beings sharing that same location sukhino: centered in happiness and joy, free from suffering bhav: the divine mood or state of unified existence antu: may it be so, it must be so (antu used as an ending here transforms this mantra into a powerful pledge)
