Although I did not personally know your father, we did have some interesting posts online. I had considered his opinions to be that of a much younger man. Maybe that is what is was... in his heart and soul.
I hope his spirit can travel to meet our friends who have passed into the energy of the universe, sometimes called heaven. From this time forth, I shall remember him for the man on earth, and I will remember him as being reborn in heaven, where he can meet and talk to all the great spirits who have left this earth.
My sorrow is for your loss, but my heart smiles when I think of his spiritual rebirth.
I pray his spirit will watch over all of us.
