AUM saha navavatu, saha nau bhunaktu
Saha veeryam karvaavahai
Tejasvi naa vadhita mastu
maa vid vishaa va hai
AUM shaantih, shaantih, shaantih

Meaning of the Sahanavavatu Mantra:
Let us together (-saha) be protected (-na vavatu) and let us together be nourished (-bhunaktu) by God's blessings. Let us together join our mental forces in strength (-veeryam) for the benefit of humanity (-karvaa vahai). Let our efforts at learning be luminous (-tejasvi) and filled with joy, and endowed with the force of purpose (-vadhita mastu). Let us never (-maa) be poisoned (-vishaa) with the seeds of hatred for anyone. Let there be peace and serenity (-shaantih) in all the three universes.
