Karma is activity. Activity is ever and always the conduct (a particular thought, word, or deed) of a particular sentient being at a particular location-time. When the conduct of a sentient being harmonizes with reality (truth, Buddha-Dharma) as it is here-now, that is enlightenment (‘Buddhahood’). When the conduct of a sentient being diverges from the truth here-now, that is delusion (‘ordinary being’). To be deluded is to be ‘bound to suffering’, to be enlightened is to be ‘liberated from suffering’ – the former ‘suffer’ the consequences of here-now of their actions (karma), the latter ‘utilize’ the liberating potential of action (karma) here-now. For karma is never some ‘general’ reality that exists separate from actual distinct actions of particular beings here-now; ‘karma itself’ (as an independent thing or entity) does not exist. Likewise, the only real ‘delusion’ in the universe are the particular ‘deluded thoughts, words, or deeds’ of actual sentient beings here-now; the only ‘realization’ is that manifest as particular thoughts, words, or deeds of sentient beings here-now.
Delusion, remember, is something that does not exist. Realization, remember, is something that does not exist.
