Once you’ve gotten to a neutral/empty state, it is far easier to engage a heightened one like compassion; it is easier to bring in pure joy or love or gratitude or any of the elevated emotional states. That’s true because those emotions are already profoundly coherent. And when you’ve moved through the meditative process and produce a brain-wave state that reflects this purity, then you will begin to overcome the body, the environment, and time, which once produced your self-limiting emotional states. They will no longer control you; instead, you will control them.
