It isn’t hard to see how human evolution corresponds to the evolution of the earth!
"It isn’t hard to see how human evolution corresponds to the evolution of the earth! Yes, most men and women are like earths being formed: they have not yet succeeded in making their inner ground really stable – it is always bubbling up, being shaken and fissured by volcanic eruptions. And the Lord, who would so love to come with his angels and establish his dwelling within them, still has to wait for them to settle down.
The Lord works within all creatures, but they are not all at the same stage of formation, that is, not all in the primary, secondary or tertiary era, and so on. This is why certain earths are still inhabited by dinosaurs, while others have orchards and cultivated fields. Spiritual Masters are beings who have worked on their own earth for a long time, which is why they come to move the ‘plough of the world’ forward, to lift humanity’s karma."
