BṚHADĀRAṆYAKA UPANISHAD · 3.7.14
यस् तेजसि तिष्ठंस् तेजसो ऽन्तरो यं तेजो न वेद यस्य तेजः शरीरं यस् तेजो ऽन्तरो यमयत्य् एष त आत्मान्तर्याम्य् अमृतः । इत्यधिदैवतम् ॥
yas tejasi tiṣṭhaṃs tejaso ’ntaro yaṃ tejo na veda yasya tejaḥ śarīraṃ yas tejo ’ntaro yamayaty eṣa ta ātmāntaryāmy amṛtaḥ । ityadhidaivatam ॥
'He who dwells in the light (tegas), and within the light, whom the light does not know, whose body the light is, and who pulls (rules) the light within, he is thy Self, the puller (ruler) within, the immortal.' So far with respect to the gods (adhidaivatam); now with respect to beings (adhibhûtam).
