BṚHADĀRAṆYAKA UPANISHAD · 3.7.3

यः पृथिव्यां तिष्ठन् पृथिव्या अन्तरो यं पृथिवी न वेद यस्य पृथिवी शरीरं यः पृथिवीम् अन्तरो यमयत्य् एष त आत्मान्तर्याम्य् अमृतः ॥

yaḥ pṛthivyāṃ tiṣṭhan pṛthivyā antaro yaṃ pṛthivī na veda yasya pṛthivī śarīraṃ yaḥ pṛthivīm antaro yamayaty eṣa ta ātmāntaryāmy amṛtaḥ ॥

Yâgñavalkya said: 'He who dwells in the earth, and within the earth, whom the earth does not know, whose body the earth is, and who pulls (rules) the earth within, he is thy Self, the puller (ruler) within, the immortal.'
