If there is no permanent, unchanging entity or substance like Self or Soul (Ātman), what is it that can re-exist or be reborn after death? Before we go on to life after death, let us consider what this life is, and how it continues now. What we call life, as we have so often repeated, 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.’ Thus, even now during this lifetime, 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 nonfunctioning of the body?

When this physical body is no more capable of functioning, energies do not die with it, but continue to take some other shape or form, which we call another life. In a child all the physical, mental and intellectual faculties are tender and weak, but they have within them the potentiality of producing a full grown man. Physical and mental energies which constitute the so-called being have within themselves the power to take a new form, and grow gradually and gather force to the full.
