“We are practicing sitting meditation and we see a bowl of tomato soup in your mind’s eye, so we think that is wrong practice, because we are supposed to be mindful of our breathing. But if we practice mindfulness, we will say, ‘I am breathing in and I am thinking about tomato soup.’ That is Right Mindfulness already. Rightness or wrongness is not objective. It is subjective.”
– Thich Nhat Hanh, Linji School, Zen.
