अक्षरस्यैव दुर्लक्ष्यत्वात्पुन पुनर्वचन सुलक्षणार्थम् ।यस्मिन् अक्षरे पुरुषे द्यौ पृथिवी च अन्तरिक्ष च ओत समर्पित मनश्च सह प्राणै करणै अन्यै सर्वै, तमेव सर्वा-श्रयमेकमद्वितीय जानथ जानीत हे शिष्या ।आत्मान प्रत्यक्स्वरूप युष्माक सर्वप्राणिना च ज्ञात्वा च अन्यावाच अपरविद्यारूपा विमुञ्चथ विमुञ्चत परित्यजत ।तत्प्रकाशय च सर्व कर्म ससाधनम् ।यत अमृतस्य एषसेतु एतदात्मज्ञानममृतस्यामृतत्वस्य मोक्षस्य प्राप्तये सेतुरिवसेतु, ससारमहोदधेरुत्तरणहेतुत्वात्, तथा च श्रुत्यन्तरम्—'तमेव विदित्वाति मृत्युमेति नान्य पन्था विद्यतेऽयनाय'इति ॥
In plain words
Because this imperishable reality is subtle and hard to grasp, the teaching is repeated so it may be clearly understood. In that imperishable spirit, heaven, earth, and atmosphere are woven, along with the mind and all the vital senses. Know Him alone as the one non-dual Self, the support of all. Renounce all other speech and lesser knowledge, along with all ritual actions and their means; for this knowledge of the Self is the bridge to immortality, enabling you to cross the vast ocean of worldly suffering.

Abandon other words, which are forms of lower knowledge...
