Shanti Mantra is taken from the krishna Yajurveda Taittiriya Upanishad (2.2.2) . It is usually recited in schools as prayer before the start of the classes in schools
Oṁ Saha nāvavatu saha nau bhunaktu Saha vīryam karavāvahai Tejasvi nāvadhītamastu Mā vidviṣāvahai Oṁ Shāntiḥ, Shāntiḥ, Shāntiḥ
Om, May we all be protected May we all be nourished May we work together with great energy May our intelect be sharpened (may our study be effective) Let there be no Animosity amongst us Om, peace (in me), peace (in nature), peace (in divine forces)
ॐ सह नाववतु। सह नौ भुनक्तु। सह वीर्यं करवावहै। तेजस्वि नावधीतमस्तु मा विद्विषावहै। ॐ शान्तिः शान्तिः शान्तिः ॥
