We had a Sanskrit activity in school. I learnt this for it……
ॐ सह नाववतु । सह नौ भुनक्तु ।
सह वीर्यं करवावहै ।
तेजस्विनावधीतमस्तु मा विद्विषावहै ॥
ॐ शान्तिः ! शान्तिः ! शान्तिः !!
It means: May He protect both of us – the teacher and student. May He nourish both of us. May we both acquire the capacity (to study and understand the scriptures). May our study be brilliant. May we not argue with each other. Om peace, peace, peace.
