The cause is right now; the result is at the moment of death. When the resultant action is already manifest, how can you fear? Fear is over the past and present; since the past had a present, the present must have a past. Since there has been enlightenment in the past, there must also be enlightenment in the present. If you can attain now and forever the single moment of present awareness, and this one moment of awareness is not governed by anything at all, whether existent or nonexistent, then from the past and the present the Buddha is just human, and humans are just Buddhas.
