" Consider this, my son: this earth-life is a little time, of which
a third is spent asleep. What went before it, and what cometh after,
are a long time--verily a time too long for measurement. Shall we
be of the herd who say that dreams are a delusion because waking
we can not interpret them in terms of common speech? Or shall we,
rather than pretend to have more knowledge than the gods, admit
that possibly some dreams may link us with that universe from which
we came into a temporary world, and into which we must inevitably
yield ourselves again? Some dreams are memories, it may be, of
experience gained in the infinity of time before the world was.
And the wisest--aye, the very wisest of us--is he altogether sure
that all earth-life is not a dream.--From The Book Of The Sayings
Of Tsiang Samdup "
