Say not in grief that she is no more but say in thankfulness that she was. A death is not the extinguishing of a light, but the putting out of the lamp because the dawn has come.
This is an occasional random reading that may be suitable for a eulogy.
We Bereaved Are Not Alone - Helen Keller
We bereaved are not alone.
We belong to the largest company in all the world, the company of those who have known suffering.
When it seems that our sorrow is to great to be borne, let us think of the great family of the heavy hearted into which our grief has given us entrance, and inevitably, we will feel about us their arms, their sympathy, their understanding.
Believe, when you are most unhappy, that there is something for you to do in the world.
So long as you can sweeten another's pain, life is not in vain.
