Two years ago I designed and performed my own death and rebirth ceremony as a self initiation into the mysteries. I think this has shifted my relationship with death in some ways, but in other ways, I understand my own initiation as entirely symbolic and a very poor imitation of the reality of death. I can say that I have little fear of death, but I have a deep skepticism even about my own claim.
I see the lack of fear of death as coming from one of two sources, either one has had a first hand encounter with death and understands it absolutely as a reality and made peace with that reality, or else one has never truly faced their own death and have created a happy system of evasion, of which I can label absolute faith in an afterlife as one of many possible variations.
I say the above, and am immediately brought to my own inner conflict on the matter. I do believe in an afterlife, and could argue that my faith in one is as strong as anyone else's... still this belief is a happy evasion, it's a self imposed barrier between myself and the true nature of death, which I am reconciled with as an eventuality, but completely ignorant of as a reality. I can state lack of fear, but lack of fear is ignorance in this case, and not wisdom. I meditate on death. I have conversations with death. Still death remains an alien to me. I love life, despite the ups and downs, the thrills and disappointments. The only thing I can say definitely is that the more time I spend with death the less fear I have of life, and that has its own special value. As far as death is concerned I will have to wait and see, but for now my waiting is calm rather than anxious, curious rather than despairing.
