You, Me, All Are Immortal.

In fact everybody is immortal but we are living in a mortal body and we are so close to the body that the identity arises.
There is no distance to see the body as separate. We are so immersed in the body, rooted in the body, that we start feeling we are the body and then the problem arises:

we start becoming afraid of death. Then all the fears, all the nightmares, come in its wake.

Awareness creates the distance between you and your body. It makes you watchful of both your own body and mind.
