Two months ago my mother was killed in a tragic accident that my father and I were witness to. In the past two months I have had trouble coming to terms with her extremely sudden death and its impacts on my life. I returned to my Zazen practice a few days after the accident and have found momentary peace there but my mind is stormy and restless when I am not sitting. I understood concepts of impermanence and non-attachment but having someone close to me killed before my eyes made me realize how attached I really was. I find myself thinking more about the four noble truths but I am at a loss on how to proceed. I am writing to ask all of your opinions of death, attachment, impermanence, and possible life after death.
