the Maker

A man has two conditions: in this world and in the world beyond. But there is also a twilight juncture: the condition of sleep (or dream, svapna). In this twilight juncture, one sees both of the other conditions, this world and the other world . . . When someone falls asleep, he takes the stuff of the entire world and he himself takes it apart, and he himself builds it up, and by his own bright light he dreams . . . There are no chariots there, no harnessings, no roads; but he emits chariots, harnessings, and roads. There are no joys, happinesses, or delights there; but he emits joys, happinesses, and delights. There are no ponds, lotus-pools, or flowing streams there, but he emits ponds, lotus-pools, and flowing streams. For he is the Maker (Kartr).
