There's no indication or hint about the material world in my painting. No, I don't paint about the world. Everybody else is painting about the world.… - Agnes Martin

I am simply painting concrete representation of abstract emotions such as innocent love, ordinary happiness. I do want an emotional response. And I paint about emotions, not about lines. The truth is that it's not the lines that express the emotion. It's the scale of the composition. You know, if you go into a room that has perfect scale, you feel it.. .If the painting has perfect scale, it moves you. And you have different scale to show different emotions. It's the space between the lines that counts.

When I first made a grid I happened to be thinking of the innocence of trees and then this grid came into my mind and I thought it represented innocence, and I still do, and so I painted it and then I was satisfied. I thought, this is my vision.

You sort of underestimate the human being when you say that every least thing that is an abstract experience is spiritual. It isn't. It's just your real self. You can be capable of fantastic abstract experiences, right in this life.
