The other side of life is very real, believe me. But we must lift upward in our thinking and realize that all life has a beginning in a place that we are not familiar with until we return to the spiritual side of existance to experience it and know from where it all begins. The problem is, once we get here and realize this side of life we forget from whence we came. Two life styles are as real as the other. They both began at the conception of thought.
Life is thought, thought is manifested into reality.
This is not just a theory, this is from 23 years of working with the dead and dying, and the afterlife teaching I have experienced.
