"When you sit in the full lotus position, your left foot is on your right thigh, and your right foot is on your left thigh. When we cross our legs like this, even though we have a right leg and a left leg, they have become one. The position expresses the oneness of duality: not two, and not one. This is the most important teaching: not two, and not one. Our body and mind are not two and not one."
from Zen Mind, Beginner’s Mind by Shunryu Suzuki
