Death
It may be hard for some to comprehend, but Death is a woman and so is Life. It is through women that all life enters, so naturally it would be through women that all life exits.
In Judaism she is called Azrael. In Islam she is known as Malak al-Mud. Shintoism has Izanami, the goddess of both death and life.
The Maori have goddess Hine-Nui-te-po. The trickster demigod Maui wanted to make humans immortal, so he transformed himself into a worm. He then attempted to enter her through her vagina and leave through her mouth, thus reversing the natural cycle of birth and death. Hine-Nui-te-po was awoken at once, and crushed Maui to death with teeth inside her vagina. He is considered to be the first man to die.
While many view her in a negative life, she is our liberator. Like how the Hindu goddess Kali teaches us that we our beings of spirit, not of flesh. She liberates us from delusions and false realities. We are freed from our suffering because of her.
Death cannot be reversed, and neither can life. It is fruitless to wish you had never been born, because you are here now. And that is all that matters.
