Do not expect unconsciousness and annihilation.

Above all things, do not expect—which is to demand—

Unconsciousness and annihilation. 

You cannot annihilate the unit of force, which you are, but you can—by self-suggestion—put it to sleep, for ages. 

Go out of life with the determination to retain consciousness—

And you will retain it.

When the time comes for you to enter that rest, which a certain school of thought has called devachan, you will enter it—but that time will not be immediately after you go out.

On finally reaching that state, you will, as a matter of course, relive, in dream, your former earthly life, and assimilate its experiences, but—by that time—you will have got rid of the desire personally to take part, as a spirit, in the lives of those you have left behind.
