In a letter I wrote to a friend, I talk about how the concept of emptiness gives such a negative connotation to the actual beginning of things. The reason why Nothing and Absence is often associated with an agonizing sense of lack is because too much emphasis is given on What Should Be There and Presence. If only we learned to take things as they are, we would be able to overcome Loss painlessly precisely because Loss as a concept would cease to exist in itself.
There was nothing to lose to begin with because there was only Nothing in the beginning.
The song is an appendage to the thought. It is not the point of the post but maybe necessary to the mood and feeling. It could stand on its own, it can also be done without.
