Clearly he has a strong spirit and it has kept him moving, that is awesome, sounds like a helluva person.
While homeless I spent a lot of time meditating on death, and the metabolic process as our bodies return to the earth, water to sky..energy transforming. I lost several relatives in these years past.. then and especially in difficult times they are always near. I will and do talk to them- and they talk back in their way. I have seen some amazing things ! (I even considered being a mortician at one point.- but I hate gore) I have a background in orthodox Christianity, which unlike some newer churches teaches how to remain in contact and communion beyond death. Well.. I got that out of it anyway. I'm weird.. I could talk and meditate about death/how amazing life is ..believing on so many levels, its just a metamorphosis.. we are caterpillars now.
There is a book I would recommend, that is not about death..but rather an amazing energy that lives in us that could prove inspirational and fairly short read. I don't know if I can tell you about it here? Written by a doctor.. This is only my second day here, I'll see if I can message you a link.
Seriously, my relatives jointly told me in a dream I was pregnant- before I knew.. Also the night my uncle passed I had a dream and was awoken to the phone call, simultaneously. I have sooo many stories that are just.. a blessing to me. I suppose I don't have to many friends on this plane of existence however being so ..weird. :/ (And from my experience it does not matter whether they were "practicing Christians"- still seeing miracles surround em.) Ahh.. but ya'll know I'm a bit nuts.
