Śrīmad-Bhāgavatam · Text 11.7.9
Who is speaking and story frame
तस्माद् युक्तेन्द्रियग्रामो युक्तचित्त इदम् जगत् ।
आत्मनीक्षस्व विततमात्मानं मय्यधीश्वरे ॥ ९ ॥
tasmād yuktendriya-grāmo
yukta-citta idaṁ jagat
ātmanīkṣasva vitatam
ātmānaṁ mayy adhīśvare
Therefore, bringing all your senses under control and thus subduing the mind, you should see the entire world as situated within the self, who is expanded everywhere, and you should also see this individual self within Me, the Supreme Personality of Godhead.
