Spiritual Choice
For me it started as a simple adolescent way to break from authority, but I've been a vegetarian now for seven years and I feel healthier and oddly, kinder when I do not eat meat. It has actually turned into a spiritual preference.
I see eating meat as an inherently aggressive act, and when I refrain from that I feel more I have a more friendly, open disposition. Perhaps it now goes hand-in-hand with my choice to become a buddhist, but in all I realize it is a healthier lifestyle. I am more aware of what I am eating, seeing as I have to be sure I ingest enough iron and protein, and that has led to better (and more inventive) meals on my part.
I do not need meat to live, and therefore it becomes not a necessity, but a choice in itself. With a natural taste for all things vegetable, I don't miss meat much at all, and even my omnivore friends have responded well to my veggie dishes. I think going vegetarian is something everyone should at least try once in their lives. It makes a real difference in the way you relate to your food.
