Energy is prakrutha in micro level and Energy is aprakrutha in Macro level!
1) Universal Level:
Energy is prakrutha!
The mass and energy are interrelated.
Cosmic Level deals with the type of energy that exists here in this material world - electrical, mechanical, thermal, kinetic, gravitational, potential, magnetic etc
One of Einstein's great insights was to realize that matter and energy are really different forms of the same thing. Matter can be turned into energy, and energy into matter.
For example, consider a simple hydrogen atom, basically composed of a single proton. This subatomic particle has a mass of
0.000 000 000 000 000 000 000 000 001 672 kg
This is a tiny mass indeed. But in everyday quantities of matter there are a lot of atoms! For instance, in one kilogram of pure water, the mass of hydrogen atoms amounts to just slightly more than 111 grams, or 0.111 kg.
Einstein's formula tells us the amount of energy this mass would be equivalent to, if it were all suddenly turned into energy. It says that to find the energy, you multiply the mass by the square of the speed of light, this number being 300,000,000 meters per second (a very large number):
= 0.111 x 300,000,000 x 300,000,000
= 10,000,000,000,000,000 Joules
This is an incredible amount of energy! A Joule is not a large unit of energy ... one Joule is about the energy released when you drop a textbook to the floor. But the amount of energy in 30 grams of hydrogen atoms is equivalent to burning hundreds of thousands of gallons of gasoline!
The Big Bang theory is the prevailing cosmological model that explains the early development of the Universe.
2) Cosmic Level and Beyond:
Energy is aprakrutha:
अप्रकृत aprakRta adj. not belonging to the matter
(i) Abheda, Bheda and Ghataka Srutis:
Paramatma - Cosmic energy - Eswara
Jivatma - local Energy - Chit
Materials - Achit
The Abheda Sruthis seems to state that the universe (all chit and achit entities) and the Brahman are one and the same. They seem to convey the identity of the universe and the Brahman.
"Tat Tvam Asi" seems to tell that the Jeevaatman (Chit) and the Brahman (Iswara) are one and the same.
The Bhedha Sruthis seems to categorically declare the difference between the Brahman and the universe.
"Pradhaana Kshetragjnya pathir gunesha:" means that Iswara is the Lord is of Achit and Chit, and Iswara is with divine qualities namely Power, Strength, Lordship, Firmness, Knowledge and Glory which are beyond the reach of all words and sense organs.
The Ghataka Sruthi synchronizes the above two types of sruthis and resolves the apparent contradiction in the above mentioned two types of Sruthis.
The Ghataka Sruthi declares that the Brahman is the inner controler (Antaryaamin - Aatma) Soul present inside all chit and achit entities and all chit and achit entities are the body (Sareeram) of Brahman. This Sareera-atma Bhaavam (body-soul) relationship between the universe and the Brahman is conveyed by the "Ghataka Sruthi" This makes it clear that both the Abheda and Bheda sruthis convey the same meaning without any contradiction.
(ii) Taittiriya Upanishad - Anandavalli:
One unit of Brahman ananda is equal to,10 power 20 times of the Unit-Bliss from all the wealth in the world.
The Material Bliss from all the wealth in the world is insignificant to the Spiritual Bliss (Brahman ananda, The Cosmic Energy).
