Śrīmad-Bhāgavatam · Text 11.7.42
Who is speaking and story frame
अन्तर्हितश्च स्थिरजङ्गमेषु
ब्रह्मात्मभावेन समन्वयेन ।
व्याप्त्याव्यवच्छेदमसङ्गमात्मनो
मुनिर्नभस्त्वं विततस्य भावयेत् ॥ ४२ ॥
antarhitaś ca sthira-jaṅgameṣu
brahmātma-bhāvena samanvayena
vyāptyāvyavacchedam asaṅgam ātmano
munir nabhastvaṁ vitatasya bhāvayet
A thoughtful sage, even while living within a material body, should understand himself to be pure spirit soul. Similarly, one should see that the spirit soul enters within all forms of life, both moving and nonmoving, and that the individual souls are thus all-pervading. The sage should further observe that the Supreme Personality of Godhead, as the Supersoul, is simultaneously present within all things. Both the individual soul and the Supersoul can be understood by comparing them to the nature of the sky: although the sky extends everywhere and everything rests within the sky, the sky does not mix with anything, nor can it be divided by anything.
