I spent most of my life trying to disown my parents and now that they are passed, I have discovered how much they were simply the mirrors I chose in this incarnation to learn the next step toward perfect freedom. As to my own son, I realized very soon after he was born that I needed to humble myself in the experience that I had nothing to teach him, that I was merely a tour guide, pointing out this and that, along our short path together. Only now, as he is moving away to follow his own path, have I allowed myself the freedom to know that sharing, without attachment or the expectation that what I have to offer is of any interest to him whatsoever, is the greatest lesson I have left to teach, not only to my family or with anyone else with whom I share a path, but also to myself.
From a discussion on freedom and family with Domo Geshe Rinpoche on Facebook
The very best use of life
...is to transform to the awakened state. Next best is to develop qualities. Next best and skillful use of life is gaining deep connection to capable mentor who promises to hold you and care for you even after your passing. The least useful is to say you are a Christian or a Buddhist and expect that to save you!
