Everything in Nature has an identity. We, as a part of Nature, therefore, need an identity.
Question is, what kind of identity?
In the quest to earn a livelihood, and create a happy life, people move from one place to another, only to find that they are alien to both the place they left, and the place where they created a home.
In war-torn countries, people have been uprooted from their homes and bunged into refugee camps, where they live with no home/land of their own in sight.
In countries which have been fractured into distinctly separate units, people who lived together in harmony and happiness, suddenly find they have to shift to either side of lines drawn by war-blinded-hate-fed humans.
In frightening situations when for the sake of winning freedom from despots, freedom-fighters have enslaved and tortured men and women beyond all believable and imaginable limits, because all of a sudden the men and women who were neighbors, now look like enemy.
In mad twists of fate, people of the same race have turned on each other because they were followers of this wise man, or that prophet, or this god,or that goddess, all of whom, incidentally, preached brotherhood of man.
So, what identity are we looking at? And yet, we need an identity, if only to feel that we are real...
A leaf that grows on a branch is a leaf, and when it falls it is still a leaf, and the ground where it falls belongs as much to it as to whoever else treads on it...
