Thank you. Also, on the idea of psychopomp, Buddhists have the idea of the Boddhisattva, which is a person seeking enlightenment who pauses on the way they've learned so far. They intend to help others who aren't as far along. Buddhists also have protective and temple-defending warrior spirits who speak to and might be regarded as psychopomps to the more warrior-path inclined.
In a different tradition, a more formal psychopomp-spirit might be "permanent," "adult", unchanging-- they're already developed to their full extent, the powers they exert are not going to change or develop further. Angels or devils might fall into this kind of category.
But I'm wondering how often a more plastic, developing, changeable soul on a path of pretty advanced skills might look pretty ancient and immovable to a younger, more fragile human being.
Some people almost treat the Dalai Lama this way.
This claims the quote is a Hindu saying, but I can't speak to the true Provenance of it, especially given the kinds of things the Innerwebz put into the mouths of Einstein and Abe Lincoln.
