Using age as an example now, it may seem to you that you are a given age, that within your subjective experience it must be paramount, that regardless of your age you are to some extent closed off from the experience of being any other age. In some simultaneous existences you are very young, however, and in others very old. Some of your physical cells are brand new, so to speak - the regeneration of fresh life is physically within you; in your terms this is true not only until your death but even after it, when your hair and nails can still grow. Identify then with the constantly new energy alive within you in this now of your being (very intently) and realize that on all levels you are biologically and psychologically connected with that greater identity that is your own.
You may take a break.
