The image and the short verse in the link are spectacular. Martin Buber wrote complex prose which was poetic. His central point in his seminal work I and Thou was we become who we are in relationship with ourselves, others, and the world. He has a beautiful section about our relationship with trees. In our relationships, we become unique. We are not duplicates of anyone else.
We are who we are because of our relationships, the impact they have on us, and the sense we make of them. Sometimes, more often than not I imagine, the relationships go unnoticed and are taken-for-granted just as our uniqueness is. We become whats in the world rather than a particular who in the world. We might even fall victim to seeing ourselves as whats, as products, rather than that unique person who is only expressed in our particular whoness.
In a world driven by standardization and conformity to standards, it is difficult to find one’s voice and express one’s self through that voice.
