Taittirīyopaniṣat 03.01
ॐ सह नाववतु। सह नौ भुनक्तु। सह वीर्यं करवावहै। तेजस्विनावधीतमस्तु मा विद्विषावहै॥ ॐ शान्तिः शान्तिः शान्तिः ॥१॥
Om, may we be protected together. May we be nourished together. May we work together with great energy. May our study be brilliant. May we not hate each other. Om, peace, peace, peace.
ॐ भृगुर्वै वारुणिः। वरुणं पितरमुपससार। अधीहि भगवो ब्रह्मेति। तस्मा एतत् प्रोवाच। अन्नं प्राणं चक्षुः श्रोत्रं मनो वाचमिति। तगं होवाच। यतो वा इमानि भूतानि जायन्ते। येन जातानि जीवन्ति। यत् प्रयन्त्यभिसंविशन्ति। तद् विजिज्ञासस्व। तद् ब्रह्मेति ॥१॥
Om. Bhrigu, the son of Varuna, approached his father Varuna and said, 'Venerable one, teach me Brahman.' To him, Varuna said: 'Food, life-breath, eye, ear, mind, and speech.' Then he said: 'That from which these beings are born, by which, being born, they live, and into which they enter at departure — seek to know that. That is Brahman.'
