"Om Sahana Vavatu Sahana Bhunattu
Saha Viryam Karawavahai
Tejasvinavaditamastu
Ma Vidvishavahai
Om Shanti Shanti Shanti Om"

Translation:

Together may be be protected
Together may we be nourished
Together may we work with great energy
May our journey together be brilliant and effective
May there be no bad feelings between us
Peace, peace, peace
