Some love the ones who are near them, Others whom they have lost; But as for my opinion, I love a ghost. Her life was hard and painful, Her life was tempest-tossed, Maybe she is much happier Since she became a ghost, On my love there are no limits, To my love there is no cost, No years or hours or minutes - I love this ghost, If gates of heaven are open Or if they are closed Or if she reincarnates I love this ghost, Like butterfly and a flower, Like parasite and a host, We are eternally bound - Me and this ghost - Of what are you most proud? Of what can you most boast? I care for such things nothing: I love a ghost. These are the words I'm heeding Whenever I sorrow most: Love whom you love; as for me - I love a ghost.
You might really like chapter 6 in this book for its rather comprehensive explanation for the higher invisible realms of the afterlife. http://www.allaboutchristian.com/spirituality/
