I like Doris Lessing’s Canopus in Argos series. In Shikasta she has an agent from a highly advanced alien civilization incarnate to do useful work. This is more or less the avatar concept of the Hindus, where, say, Vishnu will periodically show up and do something useful, as a dward, or a fish, or as Krishna.
This got me to thinking about Boddhisattvas, the enlightened ones who keep coming back. What must that be like? You are a general, trying to combat darkness, so you develop a battle plan that might involve 100,000 lives. Ponder that for a moment.
We know so little, yet we think we know so much. The arrogance of this modern age is horrifying. It is death, death, death.
