One can point to the ocean whilst at the beachfront,  and even extract a drop of sea water , and examine one drop of it , although this enables one to understand something of the ocean , in reality , the combined oceans , all the oceans together , are the full expression of what the sum total of the ocean is , along with its complex currents and the life it  maintains  within the waters .
Similarly .
One can point to one person , one particle of consciousness, and understand  something of consciousness,  and such a study will give clues of God . God displays His unlimited consciousness by being fully conscious of every one of his part and parcel expansions, namely the living beings .  He is simultaneously reciprocating with everyone directly . Those who understand consciousness can understand God ,those who understand dualism by studying their own consciousness can  understand something of the ” ocean ” of God’s unlimited consciousness and something of His unlimitness energies and powers .

Translation
By Me, in My unmanifested form, this entire universe is pervaded. All beings are in Me, but I am not in them.

Srila Sridhar Swami would say , in describing God ….…that God is everywhere but nowhere . How is this ? Because God is He who is full of opulences , He can bestow bliss upon His devotees as  the original personality of Godhead , and take care of the affairs of the material energies , in one sense they are non different to Him . However, at the same time, Krishna is the original person from whom all the other forms of Divinity expand,  and He remains in Goloka Vrndavana , the spiritual worlds , the unlimited spiritual realms. So He is inside everything and simultaneously outside .

How can those placing faith in  scientific materialism or atheistic Darwinian hypothesis understand ?

But Einstein, Bohr, Schrödinger , Feynman or Teller would very well understand.

And the Harvard Prof Lisa Randall.

The concept that Krishna is everywhere but nowhere is explored in spiritual and philosophical writings in many cultures. Particularly within the framework of  the dualistic school of Hindu philosophy , as opposed to monism . This concept, often attributed to Srila Sridhar Swami, suggests that Krishna is both all-encompassing and yet transcends any specific location or limitation.
Here’s a breakdown of the concept:
Everywhere:
Krishna is seen as the ultimate reality, the underlying principle of the universe. As such, He is present in everything, pervading all space and time. This aligns with the idea of Brahman, the ultimate reality in Advaita Vedanta, which  considers God impersonal and to be one, indivisible, and the source of all existence.
The one and difference is discussed in the Srimad Bhagavatam…
At the same time as being all pervading , Krishna is beyond the limitations of the material world. He is not confined to any specific place, time, or form. This aspect of Divinity emphasizes His expansions of His  spiritual energies , the ultimate reality. It’s not limited by the duality of existence and non-existence, of the physical world.
In Essence:
The “everywhere but nowhere” concept highlights the paradoxical nature of the ultimate reality. It suggests that while Krishna is present in every aspect of the universe, He also transcends it and is not bound by the limitations of the material world.
This concept is often used to illustrate the idea that the ultimate reality is not something that can be defined or localized in the same way as ordinary objects or beings. It emphasizes the transcendence of the divine and the fact that He is beyond our comprehension. “
