Chapter III: Sleep And Death

Although the astral body during sleep experiences no ideas or thoughts in consciousness, though it is unaware of pain or pleasure or the like, yet it does not remain inactive. On the contrary, it is precisely during sleep that a most vital activity devolves upon it—an activity into which it has to enter again and again in rhythmical succession, when for a time it has been working in unison with the physical and the etheric body. A pendulum, returning to the middle after swinging left, will swing to the right through the very momentum it has gathered on the left. So it s with the astral body and the *I* or Ego which it bears within it. Having been active in the physical and etheric body for a time, for a succeeding period of time—precisely as an outcome of this activity—they need to live and move and have their being in a body-free condition, in an environment of pure soul and spirit.
