How?

Even while dying every second,
How do I feel so alive ?
living in two dimensions of time,
one that drags on and on...
And the other that speeds on,
quicker than you can say, hold on.
Learning new meanings of words everyday,
of beauty, wonder, awe, joy, dream,
of courage, love, life, future,hope..
and of fact, reality, fate, futility, misery
of despair, melancholy and nothingness..
of fear and pain, and of loss and gain..
How is it that I feel like I am
in heaven and hell at the same time!
