BṚHADĀRAṆYAKA UPANISHAD · 4.4.2
एकीभवति न पश्यतीत्य् आहुः ।
एकीभवति न जिघ्रतीत्य् आहुः ।
एकीभवति न रसयतीत्य् आहुः ।
एकीभवति न वदतीत्य् आहुः ।
एकीभवति न शृणोतीत्य् आहुः ।
एकीभवति न मनुत इत्य् आहुः ।
एकीभवति न स्पृशतीत्य् आहुः ।
एकीभवति न विजानातीत्य् आहुः ।
तस्य हैतस्य हृदयस्याग्रं प्रद्योतते ।
तेन प्रद्योतेनैष आत्मा निष्क्रामति ।
चक्षुष्टो वा मूर्ध्नो वान्येभ्यो वा शरीरदेशेभ्यः ।
तम् उत्क्रामन्तं प्राणो ऽनूत्क्रामति ।
प्राणम् अनूत्क्रामन्तं सर्वे प्राणा अनूत्क्रामन्ति ।
सविज्ञनो भवति ।
संजानम् एवान्ववक्रामति ।
तं विद्याकर्मणी समन्वारभेते पूर्वप्रज्ञा च ॥

'"He has become one," they say, "he does not see." "He has become one," they say, "he does not smell." "He has become one," they say, "he does not taste." "He has become one," they say, "he does not speak." "He has become one," they say, "he does not hear." "He has become one," they say, "he does not think." "He has become one," they say, "he does not touch." "He has become one," they say, "he does not know." The point of his heart becomes lighted up, and by that light the Self departs, either through the eye, or through the skull, or through other places of the body. And when he thus departs, life (the chief prâna) departs after him, and when life thus departs, all the other vital spirits (prânas) depart after it. He is conscious, and being conscious he follows and departs. 'Then both his knowledge and his work take hold of him, and his acquaintance with former things.'
F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
