Brahman and Atman made simple

TL;DR: Brahman outside the body == Atman inside the body.

Everything manifests from Brahman or Bhuma, and unmanifests, dissolves back into it.

Everything is real or existent.

But, the time duration of existence and non-existence of things varies.

Thus, a planet, say Earth, exists longer than a mosquito on Earth.

Non-existence precedes an individual existence and

non-existence again follows that existence. [0]

 

Space is an ill-defined and ill-definable substance or field.

Per science, space is unaffected [1] by matter - that which occupies space.

Unaffected by or unchanged by both the existence and non-existence of matter.

Matter is similarly unaffected by space.

Brahman is like space with respect to manifestation.

It is not affected by  its own manifestations.

It stays the same every-where and every-when because

space and time themselves manifest from Brahman.

And since it is the ultimate cause by definition, it is itself uncaused. [2] 

The space-matter relationship is bidirectional, i.e., space to matter and

matter to space relations.

But, neither is a cause-effect relation.

Matter does not do anything to or affect space in any way. [3]

Neither does space do anything to matter.

Consider:

1. Brahman or Bhuma is the subtlest or finest cause.

2. The gross or dense body (schoola shareera) is 

a gross or dense effect.

3. Brahman that is encapsulated or infused into, or 

Brahman that has manifested

grosser/denser bodies either 

directly - causal body or kaaraNa shareera, or 

indirectly - subtle body or sookSHma shareera,

is now termed aatma or jeeva-aatma.

Is the manifested or encapsulated (in-carne-ated, emln-fleshed) Brahman,

the jeeva, the effect, different from the cause?

Yes.

But is there any transfer in the opposite direction?

No.

NOTES

[0] Something unaffected by time, that exists independent of time, may be called eternal -

existing for every given value of time in the past, present, or future.

There may also be something existing from some particular time onwards, but

never becoming non-existent thereafter.

E.g., an extremely subtle idea or concept.

Its converse may also occur - something may have existed from the beginning of time,

but stops existing.

[1] At normal human-perceivable dimensions - neither cosmically huge nor

subatomically small, quantum.

[2] Or, trying to posit a cause leads logically to infinite regression:

Brahman manifests from Brahman Zero - B0.

B0 manifests from B-1.

B-1 manifests from B-2.

And so on.

What is the difference between Brahman and B0? 

Or B0 and B-1?

Nothing intrinsic. 

There is only a supposed or assumed cause-effect relation. 

So this infinite regression is without any benefit by way of greater simplicity or abstraction.

[3] Again, in dimensions as in [1]. Gravitational waves and

the uncertainty principle work at exponentially different scales.
