That is why we have to learn to release our cows. Many things to worry about, to be angry about, and there's no space at all inside. That is why to release the cows around us and to let go of these preoccupations inside is a very essential condition for happiness. That is the space we are talking about when we practice. I feel free.
Freedom is the real foundation of happiness.
Sometimes if you don't know how to love, love will deprive you of your freedom and deprive the person you love of her freedom. That is why space is so essential in relationship. Because of that freedom, the happiness of the Buddha cannot be measured by our mind.
