य आदित्ये तिष्ठन्नादित्यादन्तरो यमादित्यो न वेद यस्यादित्यः शरीरं य आदित्यमन्तरो यमयत्येष त आत्मान्तर्याम्यमृतः ॥३,७.९ ॥
In plain words
He who dwells in the sun, yet is within the sun, whom the sun does not know, whose body the sun is, who from within controls the sun — he is thy Self, the inner controller, the immortal.
