Our blessings focus on very fundamental parts of our diet, at least from a vegetarian perspective! We even differentiate between whether fruits and veggies come from the ground, a bush, or a tree. We also separate out grains and then distinguish the type of grain. (I also wonder why meat and dairy don't have blessings.) We even separate grape products because of the use of wine as a ritual item. But not water? Not the substance that makes up 3/4 of our bodies? A substance that we cannot live without?
I don't get it. What is the fundamental principle behind the brachot? The sources I have learned from focus so much on the laws of the brachot, and I have yet to see any theoretical discussions about them and their creation. Feel free to discuss and enlighten me.
