The following is respectfully quoted from “Naked Awareness: Practical Instructions on the Union of Mahamudra and Dzogchen” by Karma Chagmé with commentary by Gyaltrul Rinpoche
The Chapter on the Cycle of Existence of Birth and Death States 
Wherever one is born in the three realms,
That birth is dominated by karma.
Death as well is dominated by karma.
When the time comes for birth and death,
The gods gradually fall from the heavens.
Despite their great miraculous powers, they are powerless to remain.
