I had a massive heart attack, and in my belief that I was close to dying, I took the opportunity to teach my son about death. That lesson increased his faith in such a way that he completely accepted all the changes that life brings us. He learned that only the present exists. From that moment on, he began living in the present time, knowing that the future is just a possibility, and without believing all the opinions from the past. He understood that there are no guides, or masters. Each one of us is our own guru, and we can only save ourselves.
