I took a meaning from this that I'm not sure that you intended.
A mother gives birth to her children, and blood comes with the child, and blood stays in the child; her blood (and your father's blood) but mostly her's.
The pain mother's go through to birth a child; willingly to bring it into the world.
To rebirth your mother in such a way of "cutting your wrist" inviting that same pain, to later be filled with joy. Spilling your blood to reanimate your mother, as she did to you.
We know this to be in vain, no pun intended, but the thought is there nonetheless.
Anyways, I don't know the pain of losing my mother, and I really don't want to have to know it, but eventually I will. It must suck and im sorry for your loss, really I am.
