Death is an unsurpassable limit of human existence... We discover the relationship which is the basis for all feelings of reverence, fear, awe, wonder, sorrow, and deference in the face of something greater and more powerful... Only such a being-unto-death can guarantee the precondition that the Da-sein be able to free itself from its absorption in, its submission and surrender of itself to the things and relationships of everyday living and to return to itself.
