What we call life...is the combination of the Five Aggregates, a combination of physical and mental energies. These are constantly changing; they do not remain the same for two consecutive moments. Every moment they are born and they die. 'When the Aggregates arise, decay and die, O bhikkhu, every moment you are born, decay, and die.' This, even dow during this life time, every moment we are born and die, but we continue. If we can understand that in this life we can continue without a permanent, unchanging substance like Self or Soul, why can't we understand that those forces themselves can continue without a Self or a Soul behind them after the non-functioning of the body?
