Text 16] The Perfect Society: Four Spiritual Classes
73
The Supreme Personality of Godhead, in His original form, has not entered everything ( apraviṣṭaḥ ), but in His impersonal form He has entered ( praviṣṭaḥ ). Thus He has entered and not entered simultaneously. This is also explained in  Bhagavad-gītā  (9.4), wherein the Lord says:
mayā tatam idam sarvam jagad avyakta-mūrtinā mat-sthāni sarva-bhūtāni na cāham teṣv avasthitaḥ
“By Me, in My unmanifested form, this entire universe is pervaded. All beings are in Me, but I am not in them.” The Lord can defy Himself. Thus there is variety in unity ( ekatvam bahutvam ).
