Om Saha Naav[au]-Avatu

ॐ सह नाववतु । Om Saha Naav[au]-Avatu |
सह नौ भुनक्तु । Saha Nau Bhunaktu |
सह वीर्यं करवावहै । Saha Viiryam Karavaavahai |
तेजस्वि नावधीतमस्तु मा विद्विषावहै । Tejasvi Naav[au]-Adhiitam-Astu Maa Vidvissaavahai |
ॐ शान्तिः शान्तिः शान्तिः ॥ Om Shaantih Shaantih Shaantih ||

Meaning:
1: Om, May God Protect us Both (the Teacher and the Student) (during the journey of awakening our Knowledge),
2: May God Nourish us Both (with that spring of Knowledge which nourishes life when awakened),
3: May we Work Together with Energy and Vigour (cleansing ourselves with that flow of energy for the Knowledge to manifest),
4: May our Study be Enlightening (taking us towards the true Essence underlying everything), and not giving rise to Hostility (by constricting the understanding of the Essence in a particular manifestation only),
5: Om, Peace, Peace, Peace (be there in the three levels – Adhidaivika, Adhibhautika and Adhyatmika).
