Existence is the substrate Turiyam. Space-time is primal superimposition on Brahman. Body-mind is primeval superimposition on Atman.
Space-time is not the real substrate called Reality. And Existence isn't evolutionary. The body-mind is an aftereffect of Maya.
Existence is not space and space is not existence. Space is an appearance in Existence. Minus Existence, space is nothing.
The power of Brahman is Maya. Maya is not the same as Brahman (Existence) nor different from Brahman (non-existence). Thus Maya neither exists nor doesn't exist.
It's impossible to investigate the origin of Maya because our understanding is one of its effects. And there is no understanding of a cause by its effect.
An effect transcends to the state of its cause to understand itself as an effect. As the mind transcends to that state of Turiyam to see through Maya. This is called Intuition.
Beyond the Big Bang Theory of All Creation, there is Existence alone (sat eva), one only without a second (ekam eva advitiyam).
Because Existence is beyond the manifestation of names and forms, Existence is unconstrained by names and forms.
When they say 'existence is,' all that can be said about Existence has been said. For Existence is Brahman and Atman is Brahman, I am.
1. That Isvaraverse
Isvara, or Brahman reflected in the intelligent creatrix of Maya, is the Maker, The Creator, instrumental cause.
And Isvara, in relation to the appearance of matter (tamas) in that Big Creatrix, is material cause too.
And Brahman in Avidya of sattva, tamas, and rajas appears as the jiva. Brahman is creator, creation, and creature. Aham Brahmasmi.
2. That Reflexive Isvaraverse of Light
In that reflexive Isvaraverse of light, the nuclear appears, binding and forceful, like the probability of wave or particle.
The second stage of materialization is atomic. Center, order, and property appears in the form of hydrogen and its 108 transformations.
Full tamas is the molecular. Classical physics lives here. But a great turn occurs with the appearances of functional compounds
like organic chemicals and sexual hormones, foretelling the motion of plants, animals, and true gurus of the light of self-awareness.
The primordial substance of the cosmos, the source of creation, is called prakriti, the creatrix. The whys are beginningless but truth transcends time.
The creatrix is not a product of Brahman nor other than Brahman. As self-awareness is neither a product of awareness nor something other than awareness.
There are three kinds of threads weaving the net of this creatrix: intelligence (sattva), motion (rajas), and material (tamas). Like energy, the speed of light, and matter.
When the weave is pure intelligence, this creatrix is called Maya. When such a weave is then mixed with motion and matter, it's called Avidya (nescience).
Brahman reflected in Maya is Isvara, that supreme universal god. Brahman reflected in Avidya are jivas like me and you.
(see Pancadasi 1:15-17)
