If there is life after death, it cannot be a place, and we would not have a body. According to quantum theory everything comes down to a wave or a particle, in other words, energy. What is a thought? Is it so impossible that what we call soul or spirit survives as a collection of our thoughts, memory, knowledge? If you spend your life immersed in material things and pleasures of the body, what thoughts will be left when you die and there is no world and no body? There would be no life after death for such a person. But imagine an enquiringly mind, that thinks about 'higher' things, that, while enjoying the world, also practices love, service, compassion etc. and is open to always learning and discovering new things. If that mind survives the body there is no reason why it should not continue to live, and, released from a body that dictates when and where it has to be, will have endless new vistas to explore and opportunities to participitate in.
