When your body and your ego and your dreams are gone, you will know that YOU will last forever. Many think that this is accomplished through death, but NOTHING is accomplished through death because death is nothing. EVERYTHING is accomplished through life, and life is of the mind and in the Mind. The body neither lives nor dies, because it cannot contain you who ARE life. If we share the same mind, YOU CAN OVERCOME DEATH BECAUSE I DID. Death is an attempt to resolve conflict by not willing at all. Like any other impossible solution which the ego attempts, 

God did not make the body, because it is destructible, and therefore not of the Kingdom. The body is the symbol of the WHAT YOU THINK YOU ARE. It is clearly a separation device, and therefore does not exist. The Holy Spirit, as always, takes what you have made and translates it into a learning device FOR you. Again, as always, it re‐interprets what the ego uses as an argument FOR separation into an argument AGAINST it.

If the mind can heal the body, but the body cannot heal the mind, then the mind MUST BE STRONGER. Every miracle demonstrates this. We have said that the Holy Spirit is the MOTIVATION for miracles. This is because He ALWAYS tells you that ONLY the mind is real, because only the mind CAN BE SHARED. The body IS separate, and therefore CANNOT be part of you. To be of one mind is meaningful, but to be of one body is meaningless. By the laws of mind, then, the body IS meaningless.
