What is the difference between absolute and positive Samadhi?

Reading through Sekida's translation of The Blue Cliff Record I keep coming across mentions of both absolute and positive Samadhi, and I'm interested in hearing some clearer definitions of these two terms. My interpretation of them is that: - when we're in absolute samadhi we recognize the unity of reality but we haven't attained a state of pro-activity yet. Reality seems unchangeable - positive samadhi is when our meditative state becomes intrinsically tied with our everyday behavior, we embody the meditative state in everything we do, and take an active role in the world Does this sound correct?
