A simple # 2 pencil and paper is all it takes to find nirvana in the "ordinary". I believe the depth you begin to see, when drawing from observation, has the power to open up new and unknown worlds.
Drawing provides this wonderful quiet space for relaxation and meditation. And it requires a slower pace, which feels easier to fall into, for me, than this fast paced world.
What ultimately attracts me to wanting to sketch something is usually the light, how it happens to be falling on, or illuminating the subject with a special glow. Or perhaps at times can be a form of inquiry to get to know a certain subject better. Whatever the impulse, drawing and sketching feels like a place of refuge.
