Why is it that there is this deep-seated, deep-rooted feeling of existing forever and that I am not going to die. Is there something to it?
Well, the Upanishad says–perhaps you think so because, deep down in your subconscious, it looks like you know that there is some Entity which survives death, which does not end when the body ends, and since the subconscious has an inkling of it, it refuses to believe that life is going to end. This is one explanation.
Somebody told me the other day that it is because of the desire to live forever. This is also true, could be both. Why not? There is a subconscious inkling that there is an Entity that exists forever within the body, which maybe our true identity. We will come to that as we go through the Upanishad properly.
It could also be that the mind refuses to die. Why? This is so because it does not want to give up the pleasures; even though there are sorrows, the desire is to enjoy endlessly.
If you were promised, guaranteed, that when you die, you can take everything that belongs to you–all that is dear and near to you, what you love most, what you enjoy most–then do you think there will be fear of death?
The mind refuses to leave all that it is attached to. It can’t be as free as the wind because it is entangled in pleasures and depends on this enjoyment for its existence.
