Close your eyes and let the word paint a thousand pictures
This most likely refers to dreaming, which lets your mind see things on its own. This is Kanye encouraging people to let the right side of their brain go apeshit.
Ye is also leaving us with a little bit of sappiness as he talks about love and marriage (the “word” here is “bound,” i.e. marriage): The thousand pictures are the memories of everything that has led him up to this point. That’s why he references the stories about pick-ups and vacations before; they’re all part of the picture of 1000 bitches he’s thinking about before he trades them in for that one good girl. A lot of this song is about giving up that past beauty for something just as beautiful, but totally different and totally out of your control. He’s bound now.
He is also reversing the actual phrase “a picture is worth a thousand words” for his own personal spin on what we should do.
