“Ask me no more, if cast or west,
The phenix builds her spicy nest;
For unto you at last she flies,
And in your fragrant bosom dies.”

Cage the Songbird, written by Elton John, Bernie Taupin, and Davey Johnstone
Song lyrics, Blue Moves (1976)

As quoted in The Ghost-Dance Religion and Wounded Knee (1890) by James Mooney on page 721; it has been sometimes also ascribed to w:Wovoka, which seems misappropriated as Mooney himself mentions Wovoka in the same book from page 765 on.
"It is perhaps the most commonly cited piece of evidence documenting the Native American belief in Mother Earth. […]They rarely place the statement in the context in which Mooney presented it, that is, the history of millenarian movements spawned in part by the pressures Native American felt from the European-Americans' insatiable desire for land […] it is a direct response to 'white' pressures placed on native relationships with the land."

Context: We are to remember what an umpire Nature is; what a greatness, composure of depth and tolerance there is in her. You take wheat to cast into the Earth's bosom; your wheat may be mixed with chaff, chopped straw, barn-sweepings, dust and all imaginable rubbish; no matter: you cast it into the kind just Earth; she grows the wheat, — the whole rubbish she silently absorbs, shrouds it in, says nothing of the rubbish. The yellow wheat is growing there; the good Earth is silent about all the rest, — has silently turned all the rest to some benefit too, and makes no complaint about it! So everywhere in Nature! She is true and not a lie; and yet so great, and just, and motherly in her truth. She requires of a thing only that it be genuine of heart; she will protect it if so; will not, if not so. There is a soul of truth in all the things she ever gave harbor to. Alas, is not this the history of all highest Truth that comes or ever came into the world?
