I am in love with today's BOOK OF THE DAY called "Beyond: Death is not what you expected," by Dale Justice and Adam Koehler. This sci-fi book has everything I love to read as it interweaves the reality of what happens to use after we die. Take a look.
Most world cultures identify the spirit as a supernatural being, a non-physical entity such as a ghost, fairy, or angel.
Soul or psyche in Ancient Greek means "to breathe." It was believed the mental abilities of a living being: reason, character, feeling, consciousness, memory, perception, thinking, can either be mortal or immortal.
Other religions, most notably Hinduism and Jainism, hold that all living things from the smallest bacterium to the largest of mammals are the souls themselves and have their physical representative (the body) in the world. The actual self is the soul, while the body is only a mechanism to experience the karma of that life.
The afterlife is the belief that the essential part of an individual's identity or the stream of consciousness continues after the death of the physical body.
In folklore, a ghost is the soul or spirit of a dead person that can appear to the living. According to a 2009 study by the Pew Research Center, 18% of Americans claim they have seen a ghost.
The rest of us are about to.
