They could have elaborated on how to achieve this a bit more. At it's core, the thing which must be increased is awareness, of both yourself and the world (which, from the proper perspective, are one and the same). The concrete method is meditation, where the goal is to learn to make your mind perfectly still. In attempting to do so, one will become aware of the things which are not still, these things are attachments. Enlightenment is called the process of self-realization for this reason - when you become aware of how much of what you think you are is really not you at all, you will know your true self and transcend suffering. You will transcend it because you're not the one who's suffering in the first place. Suffering is essentially an identity crisis.
