Emptiness doesn't imply detachment, or that another's suffering doesn't matter. Understanding emptiness and Dependent Origination liberates love from self-concern, and opens wise ways to interact with and change the world. "The Sūtra says that outer things are not at all real – it is the mind that manifests in various ways. This teaching that dismisses outer forms was only a device to counteract the strong attachment that we have to things." –Chandrakīrti
