I don’t believe spirituality should focus on death so much as finding your enlightenment within this living plane. I also choose not to confuse spirituality with religion. I’m not sure I understand the shiny empty glass conjecture (or was it a metaphor?), but I respect your passion and thank you for sharing your beliefs.
PS: Shiny or not, a glass is never half empty nor half full. It is always full of something — if we allow ourselves to look beyond the expected, the "liquid".
