Precepts, samadhi and wisdom, just these are yang light. If you diligently cultivate precepts, samadhi and wisdom, and destroy greed, Anger and stupidity, just this is affliction turning into bodhi. And this ice then changes into water. This analogy is just an analogy. You should not, in addition, be attached to ice being bodhi.
Affliction is bodhi.
I'll just save this ice, and take it to be water. You cannot do that either. You certainly must transform it. This is just to say that each and every person can realize Buddhahood, but you must cultivate. If you do not cultivate, then you cannot realize Buddhahood.
