Śrīmad-Bhāgavatam · Text 10.14.54
Who is speaking and story frame
तस्मात् प्रियतम: स्वात्मा सर्वेषामपि देहिनाम् ।
तदर्थमेव सकलं जगदेतच्चराचरम् ॥ ५४ ॥
tasmāt priyatamaḥ svātmā
sarveṣām api dehinām
tad-artham eva sakalaṁ
jagad etac carācaram
Therefore it is his own self that is most dear to every embodied living being, and it is simply for the satisfaction of this self that the whole material creation of moving and nonmoving entities exists.
