White canvas.

At Yoga last night, the teacher was guiding us towards an "elevated state of meditation". At one point she told us to visualize a big white canvas. Check. Then we were to picture a paintbrush dipped in blue paint. Check. Now we were to paint the word PEACE into the canvas. Check. Wait! I was going through the motions of painting the word with my blue soaked paintbrush but nothing was appearing in the canvas. It was still all white. And it remained white, unspoiled.
