I was fortunate to have Geri as a sister-in-law for 49 years and expect to see her again in the larger life. The word "transition" in the first sentence summarizes my view, but I would like to quote the great Native American sage known as Silver Birch:
“No, death is a not a tragedy to those who die; it is only a tragedy to those who are left behind. To go from darkness to light is not something over which you should grieve. If you grieve, you are in reality grieving over your loss and not for one who has in truth become enfranchised. She is better off. She will no longer suffer all the ills of the human body. She will be no longer be subjected to the ravages of wasting disease. She will unfold all the gifts with which she has been endowed, and will express them free from any thwartings, and will be able to give a larger service to those who require it.”
