Mantra 1

आविः संनिहितं गुहाचरं नाम महत्पदमत्रैतत्समर्पितम् ।एजत्प्राणन्निमिषच्च यदेतज्जानथ सदसद्वरेण्यं परं विज्ञानाद्यद्वरिष्ठं प्रजानाम् ॥ १ ॥

In plain words

This is manifest, close at hand, named as moving in the cave—the great abode in which all this is placed. Know this, whatever moves, breathes, and blinks, as Sat and Asat, worthy of choice, beyond Vijñāna, the highest among beings.
