I'm pretty unsure about what's the point here, but it sounds like something really sad to me. Anyhow, I can suppose Seal used a couple who loved each other and died slowly on being exposed to nuclear chemicals (cancer?) for showing to us how fragile our existence is, so he's advicing us in a despairing way for not losing the opportunities that life gives to us for being intense ("I jade the water and I burn the fire") while we still can do it. At the same time, he seems to feel guilty for some reason for the death of that couple and I can guess it's because they are also representing his parents and he hasn't considered himself as a good son in terms of affection("Now that I understand the beauty of what they've left to hand me down" and "No-one understands./ The hand that strikes. / When just a touch of love is all the problem needed, / And when you hurt someone so much that still they die loving you"). Therefore, he seems to wish to punish himself because of this on trying to jade his life (a wish for suicide?) and the life of who used nuclear chemicals... Well, as I said before, all these interpretations are mere speculations... Forgive me if I sounded too confused here.
