An obstacle can be an obstacle or an opportunity. It's just a matter of point of view. You decide.
"Call something an obstacle, it is an obstacle. Call it an opportunity, it is an opportunity. Nothing is extraneous to the spiritual life. This is very important to understand."
I'm busy discovering and transforming my own obstacles today.
For example, creative obstacles, like not having the materials to create paintings that I have it in my mind to paint. Minimalist landscape paintings of the mountains around me. My transformation of this obstacle? To paint them with words.
