Universe is made in building blocks or levels called Tattvas in Hinduism.
The basis of all Creation is Atma. Uncreated Eternal Essence understood in Three perfections.
1. The Absolute Reality which is Formless , the Black Sun, The Void.
2. The Eternal Light that ever comes out of the Void.
3.Primal Soul Body that produces all spirits from Asuric (evil) to the most Divine (the Gods).
These three perfections is the basis of all Creation.
From this creation is issued in building blocks, which also form three main worlds
1. Siva Loka the heavenly realm.
2. The Astral realm middle realm and
3. The physical realm within the same subspace. Meaning a level also has other levels above it within itself.
There's the macro Universe the wider phenomenal Universe which is like this and the micro universe which is the individual man ,who also has these worlds within himself.
These levels or Tattvas have degrees of purity.
In Saivism 36
are recognized Tattvas ,it depends on the school of thought , some count more or less. It depends how one wants to group them but it's still the same.
In Siva Loka they are 5 pure Tattvas meaning the Eternal Light is not obscured and can be clearly seen. As you go down the impurity increases meaning there's more obscuration of the all pervading Eternal Light.
In the Astral they are seven Tattvas two of them are pure which are the ones closer to the Siva Loka the heavenly realm but in the Astral , these by chakra are by the heart and throat chakras and the other 5 are impure. Suffering is actually only in Astral and Physical realms not in the Siva Loka. The Siva Loka is where your true individual being is your soul body evolving in Eternal Light Bliss. So everything at it's core is in "heaven" so to speak,the whole creation is.
Then the physical which is more magnetic ,impure and really obscures the Eternal Light. Purity is called Actinic, Fiery,Airy Spiritual. Represented as an upside Triangle

.
Impure is magnetic , water, earth. Its material factor represented by downside triangle

.
Stars are simply pure physical bodies that allow the Eternal Light to shine through them in the Physical realm. They are transparent physical bodies. Transparency is purity. Everything you see is this Light but it's the transparency that differs. There's no intrisinc evil. Good,bad is then defined by transparency. This is of the mental mind,the intellectual mind.
You are that Light also . The Light of the Sun. Its within you. The physical body which is animal nature is impure with it's 24 impure Tattvas that make it up. That's why when you close your eyes you don't see the Light within. Its the physical body obscuring the Light of Atma.
With mental concentration training one eventually penetrates this darkness and will eventually see the Light within themselves. Mental and physical activity is what obsucures this Light. The Kundalini sleeping into the root chakra ,tied us into these bodies. Which are the astral,physical bodies or the mental , physical activity obscuring the Atma. Remember , Physical is impure.
Kids are often quite jovial because the mental and physical bodies have not fully grown to tune them out of the Bliss of their soul. When puberty hits ,that's when the animal nature of the physical is fully activated. Lack of Dharma Awareness people then strongly identify with the physical body. All problems stems from this.
The Eternal Light is first perceived at the throat chakra. Beyond this Light is the Black Sun, The Absolute Reality.
The aim of evolution is to worship God the Eternal Light like the way the stars are doing it. This how the Gods are. They are called Maha Devas.
The Eternal Light is Super conscious ,spaceless . Meaning everything you actually see is within you. In Super consciousness the most natural state, immanent nature of your true being your soul body. Everything is in one place.
Its just in the illusion of limited lower physical awareness that space exists. Yes in limited physical awareness the Sun is millions of miles away , planets and some are light years away. But where is the actual perception happening from. Its from Within. So everything you see is actually within you. That's where the perception is, you see. Its quite deep ,you need practice contemplation and actually break into contemplation which is Samadhi,within to actually get it.
Its in Super Consciousness or Cosmic Consciousness that's how one can communicate with the Gods even if in the physical space the planets they are on,are light years away from us.
In the Superconsciousness the Eternal Light of the soul , space doesn't exist.
Practice being still , that's striving to still mind and body. You will start to get it.
Imagine an Eternal Light within and meditate on it. Feel it,and think on it into certainty. Until you highly convinced that that your are Eternal Atma. Coupled with other meditation practices , physical body fitness. We build on this until Kundalini rising. To hold higher consciousness the nerves of the physical body have to be strong.
Coupled with Noble intention.
All knowledge , understanding is within yourself,this is Atma ,the All Seeing Eye of Horus. They are rishis in India ,they have learnt the physical sciences without going to school. But that's quite advanced though ,one has to have Kundalini rising , realizing the Absolute Reality within. Then they can just bring out Knowledge.
Yoga is concentration of mental activity. Practice this , tirelessly.
Everything was accomplished a long time ago. Meaning the mind is already complete in all its phases.
So true education is Know Thy Self. That's ascending awareness up the chakras into God within.
It was settled a long time ago.
