Srimad-Bhagavatam

SB Canto 8

As the air enters the vast sky and also enters the bodies of all moving and nonmoving entities, You are present everywhere, and therefore You are the knower of all.

SB 8.12.11, Translation and Purport

My Lord, You are the supreme knowledge personified. You know everything about this creation and its beginning, maintenance and annihilation, and You know all the endeavors made by the living entities, by which they are either implicated in this material world or liberated from it. As the air enters the vast sky and also enters the bodies of all moving and nonmoving entities, You are present everywhere, and therefore You are the knower of all.

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." (BS 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." (BS 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.
