Consciousness

 Still less pure energy form which can neither create nor imagine anything but only act as a medium through which the mind can interact with others and experience pleasure and pain is called the body.

For better understanding 

Ask yourself few questions.

1. Is the body you'rs or are you the body? 

2. Is the brain you'rs are you the brain?

3. Is the heart you’rs or are you the heart?

4. If your skin gets a cut what do you say -

my skin cut or I am cut?

If it’s our body it's our heart and it’s our brain then who are you? 

You are a soul - an energy which lives eternally.

Hence, our body and our soul are different.

It is said that a soul changes a body as a human changes its clothes.
