Om ! May my speech be based on (i.e. accord with) the mind; May my mind be based on speech. O Self-effulgent One, reveal Thyself to me. May you both (speech and mind) be the carriers of the Veda to me. May not all that I have heard depart from me. I shall join together (i.e. obliterate the difference of) day And night through this study. I shall utter what is verbally true; I shall utter what is mentally true. May that (Brahman) protect me; May That protect the speaker (i.e. the teacher), may That protect me; May that protect the speaker – may That protect the speaker.
Om ! Let there be Peace in me ! Let there be Peace in my environment ! Let there be Peace in the forces that act on me !
