Physicists discover that the structure of a brain cell is the same as the entire universe.

“Oh God, guide me, protect me; make of me a shining lamp and a brilliant star.” — Abdu’l-Bahá

See explanation here.

“Foolish philosophers say that the universe automatically came into being by nature. They say that in the beginning there was a chunk, and this cosmic manifestation came out of that chunk of matter. But where did this chunk come from?

“The fact is that there must be a brain, a leader, behind anything organized. We have information of this leader from the Vedas: nityo nityanam cetanas cetananam (Katha Upanisad 2.2.13). The Supreme Lord is eternal, and we are also eternal. But the Supreme Lord is one, and we are many. The Supreme Lord is very great, and we are very small. He is all-pervading and infinite, and we are finite and infinitesimal.”

“So when He said, maya tatam idam sarvam, it is not a false pride. It is fact. Simply we must have brain to understand. Maya tatam idam sarvam. Every particle, every atom, there is presence of God. That is stated in the sastra. Andantara-stha-paramanu-cayantara-stham [Bs. 5.35]. Paramanu means the atom. God is within the atom. So God is within you also. God is outside; God is within.”

“Similarly, this body, machine, is complete. And the soul is there, it is working nicely. The body is also a creation, and the universe is also a creation, and the brain which has created these things, He is complete.

“Therefore He has created these complete units. That is the idea. Purnam idam [Iso Invocation]. Purnah means complete. And because He is complete, the Creator, He has no defect; therefore He can create everything complete.”
