Light a candle with a match, or visualise doing it. Hold the wick directly above the lighted match, but not actually touching the flame. Watch carefully. The wick will begin to smoke, and will then burst into flame. Does the flame jump from the match to the candle? Is the candle flame the same as the flame on the match, or is it a different one? If we describe the process scientifically we will say that the heat from the flame on the match vaporised some paraffin wax from the candle, and the paraffin vapour ignited, producing a new flame. The two flames are separate and burn from different fuels, but are causally related.
Likewise, kamma done in one existence is like the heat. The candle is like the physical basis provided by the parents. The candle flame is like the newly born being that arises dependent upon previous causes and present supporting conditions. One important difference between rebirth and the two flames is that the last conscious moment of the previous existence ceases totally, then rebirth consciousness arises immediately afterwards. No mental or physical phenomena “transmigrate” or pass between the two existences. Rebirth is simple a process of cause and effect. Whatever potential a being has accumulated throughout many existences is preserved to give its results whenever and wherever conditions are ripe. No good or evil deeds that a being does are destroyed at death. Some may be too weak to give any effect, but any significant kammas retain their potential to give results at some point in the future, as the seeds of desert plants await the coming of rain. Powerful kammas give their results immediately, while weaker kammas may have to wait for aeons to mature.
