Intro to "freedom from attachment"

While on vacation in Greece about 10 years ago, I first discovered the idea of freedom from attachment.  There was a little used bookstore I wandered into and saw a book about Zen, so I bought it and started reading as I travelled throughout the country for 28 days.  There are so many philosophies on Zen, but the one that keeps working for me is about freedom from attachment.  It seems like we spend the first years of our life struggling to attach to someone for survival.  Our well-being depends on how well we are nurtured as children and our relationships to our parents and caregivers.  Now as an adult, the more I separate myself from attachment to beliefs, emotionally tumultuous relationships, and situations that just don't feel right - the more centered I become, and actually feel a sort of spiritual alignment within.

There doesn't seem to be a need to identify with being a particular religion or philosophical alignment.  I practiced meditation for almost 10 years before I finally reached what I call my higher self.  I started practicing yoga about 6 years ago, and this increased my ability to heal my body, mind and emotions.  I started practicing yoga in Afghanistan while on a 15 month deployment, I didn't have a teacher, but started to self teach, and a few years later studied under a teacher.  Recently I have been learning a bit more on physics, and using physics to understand my complex self in the universe.  Synchronous events keep me on a path to finding greater satisfaction in life, where I have finally surpassed the idea of suffering, and now feel a greater sense of purpose in creation, happiness and oneness.
