TAITTIRĪYA UPANISHAD · 2.invocation

हरिः ॐ । सह नाववतु । सह नौ भुनक्तु । सह वीर्यं करवावहै । तेजस्वि नावधीतमस्तु मा विद्विषावहै । ॐ शान्तिः शान्तिः शान्तिः ॥

hariḥ oṃ । saha nāvavatu । saha nau bhunaktu । saha vīryaṃ karavāvahai । tejasvi nāvadhītamastu mā vidviṣāvahai । oṃ śāntiḥ śāntiḥ śāntiḥ ॥

Hari OM. Together may He protect us, together may He possess us, together may we make unto us strength and virility. May our study be full to us of light and power. May we never hate. OM! Peace, peace, peace.
