Shavasya Upanishad starts with the mystic syllables of peace:
OM POORNAMADAH POORNAMIDAM POORNAAT POORNAMUDACHYATE; POORNASYA POORNAMAADAAYA POORNAMEVA AVASHISHYATE.
Om Shaantih Shaantih Shaantih
Meaning: This is full. From full, the full is taken, the full has come. If full is removed from full, the full alone remains.
Om peace, peace, peace.
(“Poorna” = Complete or Full.)
