astu

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन

astu — must be

Your right is to the action alone, never to its fruits. Do not act for the sake of the fruit, and do not be attached to inaction either.

सहयज्ञाः प्रजाः सृष्ट्वा पुरोवाच प्रजापतिः

astu — shall be

In the beginning the Lord of creatures brought forth beings together with sacrifice, and said: by this, flourish; let this be what grants your wishes.

वायुर्यमोऽग्निर्वरुणः शशाङ्कः प्रजापतिस्त्वं प्रपितामहश्च

astu — let there be

You are the wind, death, fire, the waters, the moon, the lord of creatures, and the great-grandfather. I bow to you a thousand times, and again, and again I bow.
