Jiva

It is the main energy of the world that is present everywhere in the world.

Everything living and non living have it.

As it's a energy it follows the law of conservation of energy.

It can neither be created nor be destroyed, but can change forms. So the amount of jiva is same as it was when the world formed.

In non living things and atmosphere it is present in a neutral state.

In living beings, It is a mixture of the energy of body, mind and soul.
