11.7.9

तस्माद् युक्तेन्द्रियग्रामो युक्तचित्त इदम् जगत् । आत्मनीक्षस्व विततमात्मानं मय्यधीश्वरे ॥ ९ ॥

tasmād yuktendriya-grāmo yukta-citta idaṁ jagat ātmanīkṣasva vitatam ātmānaṁ mayy adhīśvare

tasmāt
therefore
yukta
having brought under control
indriya-grāmaḥ
all the senses
yukta
also subduing
cittaḥ
your mind
idam
this
jagat
world
ātmani
within the individual soul
īkṣasva
you should see
vitatam
spread out (as the substance of his material enjoyment)
ātmānam
and that individual soul
mayi
in Me
adhīśvare
the supreme controller

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.
