Anan Anance, Necessities?

Heraclitus hints at a world of necessity, anan anance, necessities. So we have ananke, and then we have love and strife. And so he's, in order to get there, he has to travel,. He has to pass beyond the gates of day and night. What does that mean? Pass? In that passage i read, he says, the goddess that rules over all these things. Then he also has the goddess who speaks to him. And my proposal is that that goddess is ananke also.
