Śrīmad-Bhāgavatam · Text 2.6.17
Who is speaking and story frame
स्वधिष्ण्यं प्रतपन् प्राणो बहिश्च प्रतपत्यसौ ।
एवं विराजं प्रतपंस्तपत्यन्तर्बहि: पुमान् ॥ १७ ॥
sva-dhiṣṇyaṁ pratapan prāṇo
bahiś ca pratapaty asau
evaṁ virājaṁ pratapaṁs
tapaty antar bahiḥ pumān
The sun illuminates both internally and externally by expanding its radiation; similarly, the Supreme Personality of Godhead, by expanding His universal form, maintains everything in the creation both internally and externally.
