यस्मिन्द्यौ पृथिवी चान्तरिक्ष-मोत मनः सह प्राणैश्च सर्वैः ।तमेवैक जानथ आत्मान-मन्या वाचो विमुञ्चथामृतस्यैष सेतु ॥
In plain words
In whom the heavens, the earth, and the space between are woven, together with the mind and all the vital breaths—know that one sole Self. Give up all other speech. This is the bridge to immortality.
