As stated in the Brahma-saṁhitā:

eko ’py asau racayituṁ jagad-aṇḍa-koṭiṁ yac-chaktir asti jagad-aṇḍa-cayā yad-antaḥ aṇḍāntara-stha-paramāṇu-cayāntara-sthaṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi

“I worship the Personality of Godhead, Govinda, who by one of His plenary portions enters the existence of every universe and every atomic particle and thus manifests His infinite energy unlimitedly throughout the material creation.” ( Brahma-saṁhitā 5.35 )

ānanda-cinmaya-rasa-pratibhāvitābhis tābhir ya eva nija-rūpatayā kalābhiḥ goloka eva nivasaty akhilātma-bhūto govindam ādi-puruṣaṁ tam ahaṁ bhajāmi

“I worship Govinda, the primeval Lord, who resides in His own realm, Goloka, with Rādhā, who resembles His own spiritual figure and who embodies the ecstatic potency [ hlādinī ]. Their companions are Her confidantes, who embody extensions of Her bodily form and who are imbued and permeated with ever-blissful spiritual rasa. ” ( Brahma-saṁhitā 5.37 )

Although Govinda is always present in His abode ( goloka eva nivasati ), He is simultaneously present everywhere. Nothing is unknown to Him, and nothing can be hidden from Him. The example given here compares the Lord to the air, which is within the vast sky and within every body but still is different from everything.
