Understanding how this material single universe we are in, is built and administered by a "Person."

Materialists, impersonalist, philosophers, mental speculators and religionists, will never understand how Garbhodakasayi Visnu (God) is a Person who resides in our small single universe, without the guidance from a pure devotee of Krsna.

Our material universe exists deep inside a surrounding outer universal shell (universe) called a Brahmanda.

The Brahmanda universal shell is just one Brahmanda among trillions coming from the Body of Maha-Visnu as seen in painting below.

None devotees also find it hard to comprehend that a lotus stem with a lotus flower on top of it, has grown from Garbhodakashayi Visnu's naval where Lord Brahma, the administrator and builder of the secondary material universe inside the Brahmanda, sits on.

It is further difficult for them to have faith in Sastra (scripture) that explains all the 14 planetary systems are housed within the lotus stem coming from Garbhodaksayi Visnu's naval.

The fact is no one can understand this without the favor of Krsna's pure devotee.

They cannot understand that our small secondary single material universe, said to be 4 billion miles in diameter according to Srimad Bhagavatam's 5th canto, is surrounded and encased in a massive Brahmanda universe.

And that massive Brahmanda universe surrounding our material universe, is said to be 44 quadrillion, 444 trillion, 444 billion miles in diameter, made up of 7 or 8 material qualities and elements.

In fact, the Brahmanda universe could be double that diameter size if measured from the outer edge of the secondary material universe that is within.

All Brahmandas are come from the bodily pores and breathing of Maha-Visnu.

The below painting dipicts how the material universe really looks according to Srimad Bhagavatam but only understood by devotees.

None devotees are bewildered by this painting below.

Materialists, impersonalist, religionists and jnanis (speculators) will never understand how a "Personal God" created all these trillions of material universes, let alone understanding the perpetual youthful Spiritual worlds that are beyond this mundane temporary decaying material creation, with the blessing of Krsna's pure devotee. 

One can only understand all this by attracting the favor of a pure devotee of the Lord.

Therefore, by becoming a servant of the servant of the servant of Krsna, one can begin to understand the secrets of the universe.

Many great devotees were previously impersonalist, jnanis and materialists but somehow came in contact with a pure devotee like Srila Prabhupada and through him became devotees of the Lord Krsna.*.
