Depending on how we are attached to them, we may experience a number of different things. Most of us attach our feelings to form, and when those forms pass on we feel a loss of identity. Some will have a sense of completion, and will feel released from ties that no longer concern them. These are essentially the same lessons we receive each day. If we want the blessings in our lessons, the blessings will always be ours.
Nothing can change that truth.
The portion of our personality that is eternal, remains forever uncreated. When the ego gives up control, and stops projecting new images, the outer sheath is released. The fear of death instantly disappears. It belongs to the ego and vanishes with it. It can be a shocking experience.
